1. The High Voluminous Ponytail

The high ponytail is one of the most classic and effective styles for creating the illusion of thicker, fuller hair.

When done correctly on dirty hair, it can look incredibly polished and professional. The natural oils in unwashed hair give it the grip and texture needed to hold this style all day long.

• Flip your head upside down and gather all your hair at the crown for maximum root lift.
• Secure with a hair tie, then wrap a small section of hair around the band to hide it for a polished finish.
• Use a teasing comb to lightly backcomb the ponytail itself, adding extra volume and body.
• Mist with a light-hold hairspray to lock the style in place without weighing thin hair down.
• Pull a few face-framing pieces loose at the front to soften the look for a more professional setting.

2. The Teased Crown Updo

The teased crown updo is a go-to style for anyone wanting serious volume at the roots without the need for heavy products.

It works exceptionally well on second or third-day hair. The oils present in dirty hair actually help the teased sections hold their shape much longer.

• Section off the crown area and use a fine-tooth comb to backcomb each section toward the roots.
• Smooth the top layer gently over the teased sections to keep the style looking neat and intentional.
• Pin the back sections up into a loose chignon or French twist to create an elegant work-ready updo.
• Spray the crown lightly with a volumizing or texturizing spray before teasing for even more lift.
• Finish with a shine serum on the visible top layer only to avoid flattening the teased sections underneath.

3. Messy Bun with Volume

The messy bun is perhaps the most beloved dirty hairstyle of all time, especially for thin-haired women in a work setting.

When styled with intention, it looks effortlessly chic rather than lazy or unkempt. Dirty hair provides the perfect amount of texture and hold to make this bun look full and beautiful.

• Gather your hair into a high or mid ponytail and twist it loosely before wrapping around the base.
• Pull the bun apart gently with your fingers to expand its size and create the illusion of more hair.
• Pull out small sections at the crown and gently tug them upward to add height and volume.
• Use bobby pins to secure any loose pieces while keeping the intentionally messy aesthetic intact.
• Set with a light-hold flexible hairspray to maintain the voluminous shape throughout the workday.

4. Dry Shampoo Blowout

The dry shampoo blowout is a game-changer for thin hair on non-wash days.

It refreshes the roots, adds incredible volume, and gives the hair a freshly styled appearance.

This technique is especially powerful on fine or limp hair that tends to fall flat quickly.

• Apply dry shampoo generously at the roots, focusing on the crown and temple areas where flatness is most visible.
• Massage the dry shampoo into the scalp thoroughly using your fingertips to absorb oil and add texture.
• Flip your head upside down and use a round brush with a blow dryer to lift the roots as you dry.
• Continue blow-drying in sections, directing the airflow upward to maximize lift and volume.
• Finish with a cool shot from the dryer to set the style and add a polished, bouncy finish.

5. Half-Up Volume Twist

The half-up twist is a sophisticated and easy style that works brilliantly on dirty thin hair.

It keeps hair out of the face while showing off beautiful volume at the crown.

This style strikes the perfect balance between casual elegance and workplace professionalism.

• Take two sections from either side of the front hairline and twist them backward toward the crown.
• Secure both twists together at the back with a small clear elastic or decorative clip.
• Gently tug the twisted sections upward and outward to loosen them and create a fuller appearance.
• Backcomb the crown section lightly before twisting for extra height and volume at the top.
• Leave the rest of the hair loose and wavy or lightly curled for a polished, layered finish.

6. Dutch Braid Crown

The Dutch braid crown is a stunning style that frames the face beautifully while adding the appearance of thickness and texture to thin hair.

It works especially well on dirty hair because the texture allows the braid to grip and hold its shape. This style is professional, eye-catching, and surprisingly easy to master.

• Part the hair down the middle and begin a Dutch braid from one side of the hairline, working toward the back.
• Dutch braids are created by crossing sections under rather than over, which creates a raised, three-dimensional effect.
• After braiding both sides, meet them at the back and secure together or pin each braid across the crown for a halo effect.
• Gently tug each section of the braid outward to pancake it and create a fuller, wider appearance.
• Spray with a medium-hold hairspray to keep the braid neat and frizz-free throughout the workday.

7. Bouffant Blowout

The bouffant blowout is a classic volume technique that has stood the test of time for fine and thin hair types.

It creates dramatic height and fullness at the crown, making the hair appear significantly thicker. Dirty hair holds this style exceptionally well due to its natural grip and texture.

• Apply a volumizing root spray or mousse to damp or dry roots before styling.
• Section the crown hair and blow-dry each section using a large round brush, rolling it upward toward the scalp.
• Once dried, use a teasing comb at the roots of the crown section to create lasting height and lift.
• Smooth the top layer of hair over the teased sections gently using a soft bristle brush.
• Set the bouffant with a firm-hold hairspray and avoid touching it to keep the volume intact.

8. Fishtail Braid

The fishtail braid is an intricate-looking style that adds incredible visual texture and the appearance of thickness to fine hair.

It is much easier than it looks and creates a beautiful, bohemian-professional aesthetic. The natural oils in dirty hair help the braid sections separate and fan out beautifully.

• Divide the hair into two equal sections and begin pulling small pieces from the outer edge of each section, crossing them over to the opposite side.
• Continue this process all the way down to the ends, keeping tension consistent for a neat braid.
• Once secured at the bottom, gently tug the sides of the braid to widen and pancake it for extra volume.
• Pull small pieces loose at the top and crown to frame the face and add a relaxed, voluminous touch.
• For a work setting, keep the braid tighter and more polished at the top, loosening gradually toward the end.

9. Textured Side Part Blowout

The textured side part blowout is a sophisticated, polished hairstyle that maximizes volume on flat thin hair.

Switching the part to the opposite side instantly lifts the roots and creates natural-looking fullness. This is one of the easiest and most effective volume tricks for second-day thin hair.

• Change your part to the opposite side of where it naturally falls to lift the roots and add instant volume.
• Apply a volumizing spray at the roots and blow-dry using a large round brush from roots to ends.
• Direct the airflow along the part line to push the hair upward and away from the scalp.
• Curl the ends lightly with a large barrel curling iron or wand to add movement and body.
• Finish with a light-hold flexible hairspray and a small amount of shine serum on the mid-lengths only.

10. Low Chignon with Volume

The low chignon is the epitome of workplace elegance and works beautifully on second or third-day hair.

It creates a sleek yet voluminous look that is appropriate for even the most formal office environments.

The key is adding volume at the crown before pulling the hair back into the chignon.

• Backcomb the crown section generously before gathering the hair at the nape to create lasting volume at the top.
• Twist the hair into a low chignon and pin it securely, leaving a slightly puffy, voluminous appearance at the crown.
• Wrap a small section of hair around the hair tie or pins to conceal them for a polished, intentional look.
• Use a soft bristle brush to smooth the visible top layer of hair without disturbing the teased volume underneath.
• Set the finished style with a light mist of hairspray, focusing on the crown and any flyaways.

11. Voluminous Headband Style

Using a headband to style thin dirty hair is one of the quickest and most effective techniques for adding volume and structure.

A wide or padded headband can push the hair upward at the crown, creating an instant lift.

This style looks incredibly put-together with minimal effort, making it perfect for busy work mornings.

• Apply a texturizing spray to the roots and mid-lengths before placing the headband for extra grip and volume.
• Position a wide fabric or velvet headband about an inch back from the hairline and press it firmly into place.
• Gently pull sections of the hair forward over the headband to create a voluminous, pillowed effect at the top.
• Tuck the ends of the hair under the headband at the back for a neat, rolled finish.
• Pull small face-framing pieces forward and curl them lightly for a softer, more polished work-ready look.

12. Twisted Low Bun

The twisted low bun is a classic professional style that can be elevated beautifully on dirty hair.

The natural oils provide grip while the twisting technique creates the illusion of more hair than is actually there.

It is a clean, polished, and effortlessly chic style for any workplace.

• Divide the hair into two sections and twist each one individually in the same direction all the way to the ends.
• Wrap both twisted sections around each other to form a coiled bun at the nape of the neck.
• Secure with bobby pins, tucking the ends under the bun neatly for a polished finish.
• Gently loosen the twists slightly before pinning to add volume and a fuller appearance to the bun.
• Set with a firm-hold hairspray and smooth down any flyaways with a small amount of hair serum.

13. Volumizing Space Buns

Space buns are no longer just a festival trend — they have evolved into a modern, creative workplace style when done with a polished finish.

On thin dirty hair, they create the appearance of thick, full sections of hair pulled into two high buns. This style works especially well in creative or fashion-forward work environments.

• Divide the hair down the middle and gather each section into a high ponytail on either side of the head.
• Tease each ponytail before wrapping it around the base to create fuller, larger-looking buns.
• Secure each bun with bobby pins and gently pull the bun apart to expand and volumize it.
• Pancake the buns by pulling the outer sections outward for a more dramatic and voluminous effect.
• Use a light-hold hairspray to set the buns and keep them polished throughout the workday.

14. Root-Lifting Waves

Root-lifting waves combine the softness of beachy waves with targeted volume at the roots, making them ideal for thin hair in a professional setting.

This style looks effortless yet deliberate and adds significant body to otherwise flat fine hair. Dirty hair holds the wave pattern beautifully throughout the day.

• Apply a volumizing mousse to the roots of dry dirty hair and scrunch it in gently.
• Use a large barrel curling wand to curl sections of hair away from the face, starting from the mid-length down.
• Focus especially on curling the sections closest to the roots to ensure lift and volume at the top.
• Once all sections are curled, flip the head upside down and shake the hair loosely with your fingers.
• Mist with a texturizing sea salt spray and scrunch lightly to enhance the wave texture and volume.

15. French Twist

The French twist is a timeless, ultra-professional updo that works remarkably well on second or third-day hair.

The natural texture of dirty hair helps the twist hold its shape without requiring heavy products.

It creates a sleek, sculptural silhouette that looks polished and intentional in any office environment.

• Brush the hair back smoothly and gather it to one side, holding it taut with one hand.
• Begin twisting the hair upward into a vertical roll along the back of the head.
• Tuck the ends under the top of the twist and secure with bobby pins inserted vertically along the fold.
• Gently pull the crown hair upward and forward slightly before securing to add height and volume at the top.
• Smooth the surface of the twist with a fine-tooth comb and set with a firm-hold hairspray for all-day hold.

16. Curly Blowout with Diffuser

A diffuser blowout is one of the most effective ways to add volume and body to naturally wavy or curly thin hair on a dirty hair day.

Diffusing enhances the natural curl pattern while lifting the roots dramatically. This technique gives thin hair a full, bouncy appearance that lasts throughout the workday.

• Apply a curl-enhancing cream or mousse to the hair and scrunch gently to define the natural texture.
• Attach a diffuser to your blow dryer and set it to medium heat with low airflow to avoid frizz.
• Cup sections of hair in the diffuser bowl and hold it close to the scalp, moving in circular motions to lift the roots.
• Dry the hair in this manner until it is fully dry and the curl pattern is well-defined and lifted.
• Finish by gently separating the curls with your fingers and applying a light shine spray to reduce frizz.

17. Braided Halo with Volume

The braided halo is a romantic, crown-like style that wraps around the head and creates the illusion of significantly thicker, fuller hair.

It is incredibly work-appropriate and adds a sophisticated, polished touch to any professional outfit.

Dirty hair is ideal for this style because the texture helps the braid sit in place and hold its shape all day.

• Begin a French or Dutch braid at one side of the head near the ear and work it around the head toward the opposite ear.
• Pull each section of the braid gently outward as you go to pancake it and create a wider, fuller appearance.
• Pin the end of the braid behind the opposite ear, tucking the tail underneath the braid for a seamless finish.
• Gently tug small sections around the crown area to add extra fullness and height.
• Spray the entire halo braid with a medium-hold hairspray to secure it and tame any flyaways.

18. Teased Side Ponytail

The teased side ponytail is a retro-inspired style that is making a strong comeback in modern workplaces.

It creates an asymmetrical silhouette that is both fun and professional. On dirty thin hair, the teased sections hold their volume exceptionally well, making this style last all day.

• Apply a texturizing spray to the roots and crown area before teasing.
• Backcomb the crown and the top sections of the hair generously using a fine-tooth rattail comb.
• Smooth just the very top surface of the hair lightly before gathering it into a side ponytail at one ear.
• Wrap a small section of hair around the ponytail holder to conceal the elastic for a polished finish.
• Curl or wave the ponytail itself with a curling wand for extra volume and movement.

19. Voluminous Pixie Refresh

Even those with short pixie cuts can benefit enormously from dirty hair volume techniques.

A pixie cut on second-day hair often has more texture, lift, and character than on freshly washed hair.

With the right products and techniques, a dirty pixie can look intentionally styled and incredibly chic at work.

• Apply a small amount of dry shampoo to the roots and crown area to absorb oil and add volume and grit.
• Use a fine-tooth comb or your fingertips to lift and separate the roots at the crown for maximum height.
• Apply a small amount of pomade or wax to the fingertips and work it through the mid-lengths to define the shape.
• Use a small round brush and a blow dryer to lift individual sections at the crown for added volume.
• Finish with a light-hold hairspray or a shine spray to set the style and add a polished, intentional finish.

20. Barrel Curl Blowout

Barrel curls on dirty hair create a full-bodied, glamorous style that translates beautifully into a professional environment.

The natural oils in second-day hair allow the curls to hold their shape and bounce for hours without additional product. This style is ideal for important presentations, meetings, or events.

• Divide the hair into several sections and curl each one using a medium barrel curling iron, holding for 8 to 10 seconds.
• Alternate the direction of each curl — some toward the face and some away — to create natural-looking volume.
• Allow each curl to cool completely in your hand before releasing to ensure long-lasting hold and shape.
• Once all curls are set, use your fingers to gently separate and break them up for a fuller, more voluminous look.
• Mist with a flexible-hold hairspray and avoid brushing to maintain the curl definition and volume.

21. Knotted Half-Up Style

The knotted half-up style is a modern, trendy take on the classic half-up half-down look that adds instant visual thickness to thin hair.

It is clean, minimal, and highly appropriate for a professional environment. Dirty hair provides the grip needed to keep the knot in place throughout the day.

• Take two equal sections from either side of the front hairline and tie them together in a single overhand knot at the back of the crown.
• Pull the knot gently to tighten it and tug the front sections slightly forward to add volume and height at the crown.
• Secure the knot with a small clear elastic and pin if needed for additional hold.
• Curl or straighten the remaining loose hair to create a polished, cohesive finish with the knotted section.
• Set the knot with a light-hold spray and smooth down any flyaways with a tiny amount of hair serum.

22. Volumizing Cornrow-Inspired Style

Cornrow-inspired styles are structured, polished, and incredibly effective at creating the appearance of volume and fullness in thin hair.

The raised rows create three-dimensional texture that reads as thick and lush.

This style is long-lasting and requires very little maintenance throughout the workday.

• Part the hair into three or four even sections running from the forehead to the nape of the neck.
• Begin braiding each section very close to the scalp using a tight French or cornrow technique.
• Once all rows are braided, secure the ends at the nape with a single elastic for a clean finish.
• Gently tug each row of braids outward and upward to widen them and create a fuller, more voluminous effect.
• Spray the entire style with a firm-hold hairspray and a light sheen spray to add definition and shine.

23. Piecey Blowout

The piecey blowout is a textured, modern take on the traditional blowout that emphasizes individual sections of hair to create the look of thickness and volume.

It gives fine hair a fashionable, editorial quality that still reads as professional. Dirty hair is the absolute best base for a piecey blowout.

• Apply a texturizing paste or spray to the roots and mid-lengths of dry dirty hair.
• Use your fingers to separate the hair into piecey sections and rough-dry each one with a blow dryer on medium heat.
• Lift the roots vigorously while drying to create maximum volume at the crown.
• Once dry, use a flat iron to create subtle bends and kinks in the hair that mimic natural texture.
• Finish by separating the sections further with your fingers and setting with a light-hold flexible spray.

24. Cascading Braid with Volume Pieces

A cascading braid is a flowing, romantic style that works beautifully in professional settings when executed with clean lines and polished edges.

The cascading effect naturally draws the eye and creates an impression of lush, full hair. Dirty hair holds the braid securely while the natural oils add a healthy-looking sheen.

• Begin a loose French braid at the crown, incorporating new sections of hair as you move toward one shoulder.
• As you reach the nape, transition into a regular braid and continue down to the ends.
• Pancake the braid by pulling each section outward to dramatically widen and volumize the entire length.
• Pull small sections at the very top of the braid loose to frame the face and add a soft, voluminous crown.
• Secure the end with a small clear elastic and set the style with a medium-hold flexible hairspray.

25. Velvet Scrunchie Updo

The velvet scrunchie updo is simultaneously nostalgic and ultra-modern, combining the beloved scrunchie with strategic volume-building techniques.

A velvet or silk scrunchie adds a luxurious touch to any updo while being gentle on thin, fragile hair. This style is quick, easy, and looks impressively polished in a workplace environment.

• Tease the crown section of the hair generously before gathering it up to build volume at the top.
• Create a messy or structured bun using a large velvet scrunchie as the securing element.
• Gently pull the bun apart and tug the crown sections upward to maximize volume and size.
• Allow a few soft face-framing pieces to fall forward and curl them lightly with a curling wand.
• Finish with a light spritz of flexible hairspray to set the volume and control any flyaways.

26. Volumizing Flip Style

The classic flip is a retro-inspired style that creates bold, dramatic volume at the ends while keeping the roots lifted and full.

It is a fun, personality-filled style that looks surprisingly polished and professional. Dirty hair provides the perfect base for holding this shape throughout the day.

• Blow-dry the hair with a large round brush, curling the brush under at the ends to create an inward flip.
• Focus on lifting the roots as you dry to create fullness at the crown to balance the flipped ends.
• Once dry, go over the ends with a large barrel curling iron, rolling them under to reinforce the flip shape.
• Use a light-hold volumizing spray at the roots and a flexible hairspray on the ends to hold the flip.
• For a more modern version, flip only the ends of the front sections while leaving the back straight for contrast.

27. Braided Ponytail

The braided ponytail combines the practicality of a ponytail with the visual texture of a braid, resulting in a style that looks far thicker and more voluminous than a regular ponytail.

It is professional, polished, and works exceptionally well on dirty hair that has natural grip and texture.

This style is also very long-lasting and requires almost no touch-ups throughout the day.

• Gather the hair into a high ponytail and secure with an elastic, teasing the crown lightly before pulling it up.
• Divide the ponytail into three sections and braid it all the way to the ends, keeping tension consistent.
• Pancake the braid by gently pulling each section outward to widen and volumize it significantly.
• Wrap a small section of hair around the ponytail base to conceal the elastic for a more polished finish.
• Set the entire style with a medium-hold hairspray and smooth any flyaways with a light serum.

28. Volumizing Blowout with Hot Rollers

Hot rollers are one of the most underrated volume tools for thin hair and they work exceptionally well on dirty hair.

They create lasting lift, body, and bounce that can survive an entire workday without the need for touch-ups.

This technique produces a glamorous, full-bodied blowout that looks incredibly professional.

• Apply a volumizing spray or root lifting spray to the roots before rolling for extra lift and hold.
• Section the hair into even parts and roll each section with a large hot roller, rolling upward toward the scalp.
• Leave the rollers in for at least fifteen to twenty minutes to allow the heat to set the volume and wave.
• Remove the rollers carefully and allow the hair to cool for a few minutes before touching it.
• Once cool, use your fingers to gently separate and loosen the waves, then set with a flexible-hold hairspray.

29. Waterfall Braid

The waterfall braid is a beautifully cascading style that creates the visual impression of extremely full, lush hair.

It is delicate, romantic, and translates perfectly into a professional environment when paired with polished clothing.

The flowing sections of hair that drop through the braid create an elegant, voluminous silhouette.

• Begin a French braid at one side of the hairline, above the ear, incorporating sections from the top.
• Instead of keeping each section in the braid, drop the bottom section and pick up a new section from the top to create the waterfall effect.
• Continue across the back of the head, dropping and replacing sections as you go, until you reach the other side.
• Secure the braid with a small clear elastic or bobby pin behind the opposite ear.
• Leave the dropped waterfall sections loose and curl them lightly for a voluminous, flowing finish.

30. Faux Bob with Volume

The faux bob is a brilliant styling trick that creates the appearance of a short, voluminous bob without cutting a single strand of hair.

It works brilliantly on dirty thin hair and produces a polished, sophisticated look. This style is ideal for workplaces with a more formal dress code.

• Curl the ends of the hair inward toward the scalp using a curling iron to mimic the curved shape of a bob.
• Tuck the curled ends under the remaining hair length and pin them close to the nape with bobby pins.
• Continue tucking and pinning until all the length is hidden and the style resembles a neat, voluminous bob.
• Tease the crown section before tucking to add height and volume at the top of the faux bob.
• Set the entire style with a firm-hold hairspray and smooth the surface with a fine-tooth comb for a polished finish.

31. Pineapple Updo

The pineapple updo is a surprisingly chic and effective style for thin curly or wavy hair that needs volume on dirty hair days.

It piles all the hair at the very top of the head, creating an explosion of height and texture that frames the face beautifully.

When styled carefully, it reads as intentional and polished rather than casual.

• Flip the head upside down and gather all the hair at the very top of the head in a loose, high ponytail.
• Secure with a soft scrunchie rather than a tight elastic to avoid creasing and breakage in fine hair.
• Gently arrange the upward-facing hair into a fan or circular shape around the top of the ponytail.
• Pull small pieces at the front down slightly to soften the hairline and frame the face for a more flattering look.
• Set the style with a light hold spray and smooth any frizz with a small amount of hair serum on the fingertips.

32. Volumizing Blow-Dry with Paddle Brush

A paddle brush blow-dry is one of the most effective techniques for adding serious volume and smoothness to thin hair in a professional setting.

It creates a sleek yet full finish that looks incredibly polished. Dirty hair provides just enough texture and grip to hold the lift created by this technique all day.

• Section the hair and begin blow-drying from the nape upward, using the paddle brush to smooth and lift each section.
• Hold the blow dryer above the brush and direct the airflow downward along the hair shaft to prevent frizz.
• At the roots, use the brush to push the hair up and away from the scalp while directing the heat for maximum lift.
• Work in small sections from underneath the hair outward to build layered volume from the base up.
• Finish with a cool shot from the dryer to set the volume and add a glossy, polished shine.

33. Accessorized Clip Updo

Hair clips and barrettes are having a major fashion moment, and they can be used strategically to add structure, volume, and interest to thin dirty hair.

The right clip in the right position can lift the hair and create the illusion of significantly more volume. This style is modern, professional, and endlessly customizable.

• Tease the crown section lightly and gather the top half of the hair loosely before clipping it at the back with a large claw clip or barrette.
• Arrange the gathered section so it fans upward and outward above the clip for a dramatic, voluminous effect.
• Let the remaining lower half of the hair fall loose or curl it lightly for a polished, layered finish.
• Add smaller decorative clips along the sides to secure face-framing pieces and add additional visual interest.
• Mist the entire style with a light-hold flexible hairspray to keep it in place throughout the workday.

34. Deep-Part Curtain Bang Style

Curtain bangs parted deeply in the center create a face-framing, voluminous effect that adds both height and fullness to thin fine hair.

This style is incredibly flattering and professional, drawing attention to facial features while the body of the hair provides fullness on either side.

Dirty hair holds the parted shape beautifully and naturally.

• Create a deep side part or center part and blow-dry the bangs outward in both directions using a round brush.
• Curl the bangs lightly with a small barrel curling iron, rolling them away from the face on each side.
• Tease the crown section lightly to build height at the top before styling the rest of the hair.
• Blow-dry the body of the hair with a large round brush for volume, focusing on lifting the roots throughout.
• Set the curtain bangs and volume with a flexible-hold hairspray and a light shine spray for a polished finish.

35. Braided Updo with Crown Poof

The braided updo with a crown poof combines two powerful volume techniques into one show-stopping professional style.

The poof at the crown adds height and fullness while the braided elements at the back create structure and visual interest.

Together, they make thin hair look dramatically thicker and more luxurious.

• Tease the crown section generously and smooth just the surface before pinning it back to create a poof at the top.
• Secure the poof with crossed bobby pins at the crown and then incorporate the sides into loose braids.
• Bring the braids to the back and pin them into a low updo at the nape, tucking any ends under neatly.
• Pancake the braided sections by gently pulling them apart to add width and fullness to the overall style.
• Set with a medium-hold hairspray and use a fine-tooth comb to smooth the surface of the poof for a polished finish.

36. Smooth Voluminous Blowout

The smooth voluminous blowout is the gold standard of professional hairstyles for thin hair.

It combines maximum volume at the roots with smooth, polished ends for a sleek yet full appearance.

Dirty hair is the secret ingredient that makes this blowout last an entire workday without falling flat.

• Section the hair from ear to ear and begin blow-drying the bottom sections first, working upward to the crown.
• Use a large round brush under each section, rolling it upward while directing heat from roots to ends for maximum lift.
• At the crown, give extra attention to lifting the roots away from the scalp and holding the brush in place until the section is fully dry.
• Once all sections are dry, use the cool shot button on the dryer to set the volume and add a glossy finish.
• Finish with a light-hold volumizing hairspray and a small amount of shine serum on the mid-lengths and ends only.

37. The Effortless Shag Style

The shag hairstyle is experiencing a massive revival and is one of the most flattering and volume-boosting cuts and styles for thin-haired professionals.

The layers and texture of a shag style naturally create the illusion of significantly more hair volume.

On dirty hair, a shag can be styled quickly with minimal product for a deliberately undone yet polished result.

• Apply a small amount of texturizing spray or dry shampoo to the roots and run your fingers through to distribute it evenly.
• Use a diffuser or fingers to scrunch and lift the natural texture of the layers throughout the style.
• Flip the head upside down and shake the roots vigorously with your fingertips to maximize root lift.
• Separate the layers with your fingers and encourage each section to fall in its own direction for an effortlessly textured look.
• Finish with a light-hold flexible hairspray and avoid over-styling to maintain the natural, voluminous shag aesthetic.
