If your lengths inevitably fall flat, don’t overlook the best thickening sprays. With so many styling products on the market, it’s easy to assume they overlap—but each serves a specific purpose. “Think of a thickening spray as a little lift in a bottle,” pro hairstylist Sky Kim tells Vogue. “It coats each strand with lightweight polymers and/or volumizing ingredients that gently swell the hair shaft, making it look and feel fuller.”

In This Story


Best for Fine Hair: Rōz Hair Air Thickening Spray

Rōz Hair

Air Thickening Spray

  • Why We Love It: Flat hair doesn’t stand a chance against Roz’s thickening spray. Rugetti recommends this pick for those with fine to medium hair that lacks overall fullness. “This formula’s main ingredients are rice protein and rice water, which help to smooth, strengthen, and add shine,” Rugetti tells Vogue. “They add mushroom root extract for hair and scalp health too.” Kim agrees, noting that while this spray bolsters body for the appearance of fuller hair, it somehow manages to still feel totally weightless.
  • Editor’s Note: “This is my go-to spritz post-shower to keep my bob full and bouncy (’90s era Christy Turlington is my forever inspo). My favorite part of this spray is that it’s entirely nonsticky and never crunchy,” —Conçetta Ciarlo, beauty shopping writer
  • Key Ingredients: Glycerin, mushroom extract, rice seed protein, rice seed water, sandalwood extract
  • Best For: Fine to medium hair types

Oribe

Maximista Thickening Spray

  • Why We Love It: Sometimes your hairstyle needs both hold and height—especially for those dedicated to styling their curtain bangs every day. In that case, Oribe’s thickening spray is a reliable go-to for keeping fringe bouncy while also offering heat protection. “This formula uses thickening copolymers for instant volume and hold, amino acids to moisturize and strengthen, and the brand’s signature antioxidant blend to protect hair from UV and heat damage,” says Rugetti, noting that this pick is an excellent multitasker.
  • Editor’s Note: “During my Pamela Anderson bangs era, my hairstylist pointed me to this spray to keep my fringe lifted. Wispy ’90s bangs are notoriously finicky—they’re so lightweight that the slightest brush against your forehead can leave them greasy and flat. This Oribe spray kept mine bouncy, rounded, and full of movement, without that dreaded stickiness.” —Conçetta Ciarlo, beauty shopping writer
  • Key Ingredients: Thickening copolymers, amino acids, glycerin, Oribe antioxidant complex (watermelon, lychee, and edelweiss flower extract).

Everything You Need To Know

What does a thickening spray do?

“Hair thickening sprays are heat activated,” explains Rugetti. “They’re formulated to coat the hair shaft and create the illusion of thicker, fuller strands.” Plus, thickening sprays are often water- or alcohol-based to ensure they don’t weigh down hair. “Unlike heavy mousses or waxes, they’re lightweight and fast-drying,” she adds.

The difference between thickening spray vs. texture spray

Kim aptly points out that thickening and dry texturizing sprays are cousins, not twins. “A thickening spray gives you body and fullness from root to end; they’re great for smooth, bouncy blowouts, and used on damp hair,” she explains. “Meanwhile, a texture spray adds grip and a tousled and piecey finish, which is perfect for that beachy, undone vibe. Plus, texture sprays are used on dry hair.”

How to apply thickening spray

For the best results when using a thickening spray, make a habit of reaching for them on wash days. “Using a thickening spray on clean, damp hair (before heat styling), ensures the ingredients can properly coat and expand each strand for maximum fullness,” Rugetti explains.

She advises starting by gently towel-drying your hair to remove excess moisture, and then giving your thickening spray bottle a good shake before spritzing it from roots to ends. “For extra body, blow-dry your hair upside down or direct the airflow toward the roots. Finish with a cool shot from your dryer to set the style and add shine.”
