Remedying the issue is always worth a shot, and if nothing else has worked to give you the voluminous head of hair you deserve, here's one last thing to try: the Klorane Leave-In Spray with Flax Fiber. No, this isn't just another volumizing spray, according to reviewers, but instead some kind of "magical" concoction that gives the most stubborn head of hair its "best root lift ever." The styling and texturizing treatment instantly adds fullness and bounce to strands at the roots, putting in more work than your favorite dry shampoo could ever. Organically farmed flax fiber extract and mineral resin-like silicate not only add lift that remains for up to three days, but strengthen brittle hair for healthier growth down the line. Courtesy Shop now: $18; kloraneusa.com For the best results, the brand recommends spraying a generous amount (it won't weigh your hair down or leave it greasy) onto the roots of dry or towel-dried hair, before styling as you normally would. Hot tip: blow-dry hair upside down after applying the spray for even greater volume. The lifting spray has already garnered plenty of fans who called it "a wonderful find" after it "levitated their limp locks" and left them with "fuller, shiner hair." One reviewer claims their hair looks "twice as full" and that despite trying nearly everything, "nothing else has made such a difference." This $13 Skin-Tightening Eye Gel Is So Good, Even Estheticians Are Raving About It "This is without a doubt the best styling product I have ever used," wrote one reviewer. "My hair is not thin, but it is straight as a board, and tends to hang limp within 24 hours of shampooing. With this product, my hair is soft, shiny, and full for at least three days. If it's flat when I get up, a couple spritzes and a minute with the blow dryer makes it look shampooed again." "I have thick curly hair [that] I flat iron on the regular," said another. "This volume spray is the only product I've found that actually provides lift despite the weight of my long hair trying to flatten my roots. If you've been disappointed by every other volume spray, try this one." Do yourself and your strands a favor and grab the Klorane Leave-In Spray with Flax Fiber for $18 on the brands website. Pair it with the Klorane Strengthening Hair Growth Serum for the ultimate healthy hair duo.
