One of Taylor Swift’s hair stylists recommended it to me.

Anyone who’s hair effortlessly looks like “The Rachel,” click away — this isn’t for you. Fellow people with flat hair, listen up, because I have a simple product recommendation that’ll add major volume to your limp locks: the Unite Boosta Shampoo.

I’ve never enjoyed the feeling of flat hair, so for years I leaned on a few tools to give it a boost — hot rollers, a round brush, hairspray, you name it — and while they helped to provide some oomph, it wouldn’t last. Sure, I tried volumizing shampoos, but I never found one to have any real effect on my hair. That is, until celebrity hairstylist Riawna Capri, who has worked with Taylor Swift, Hilary Duff, and Selena Gomez, recommended Unite’s Boosta Shampoo to me. Fifteen years later, I’m still using it.

Unite’s Boosta shampoo is formulated in a super thick consistency and contains coconut oil to cleanse strands and pro-vitamin B to add moisture and volume — which it does without weighing hair down. After lathering the coconut-banana-smelling product into my locks and blow-drying (sometimes I even just rough-drying it), my strands look and feel like they’ve been lifted right up from the roots. Not only that, but the shampoo seems to add fullness everywhere — in other words, my fine hair looks full and thick from root to tip.

Unite, a now 21-year-old brand, is known and loved for its selection of cruelty-free hair products (including its super popular 7 Seconds Leave-In Conditioner, another favorite of mine) that are made without ingredients like parabens, sulfates, and harsh chemicals — and earn countless five-star reviews.

Customers on Amazon love the Boosta shampoo for how it transforms fine, thin hair into thicker, shinier strands. “This shampoo has been a lifesaver for my early mornings,” wrote one reviewer. “I'm able to wash and blow dry and I'm ready to go without a ton of products.” I agree — I don’t need to rely on any other volumizing products after using the Boosta shampoo.

“My hair is very straight but thick,” wrote another. “This shampoo gives me the volume I need to add some height to my hair.” That’s the thing — I always thought flat hair was a fine-hair-person’s problem, but I’ve learned otherwise. My mom, who has much thicker hair than me, recently tried a bottle of my Boosta and is now hooked, too.
