Pore-shrinking moisturizers, wrinkle-depleting masks, lash-lengthening serum—in the world of beauty, there are more products than we could possibly count that seem too good to be true. And, sadly, while many products with lofty claims do, in fact, fall short, one product category that regularly gets over-the-top accolades is thin hair shampoos.

Unlike many skin care and even makeup categories, hair care tends to be a bit more beneficial, given its ability to very clearly alter the hair. And, when it comes to shampoos for thin or thinning hair, that’s no exception.

“Thin hair shampoos work by bulking up the hair follicles, which will give the [immediate] appearance of thicker hair by providing extra lift and body,” explains celebrity hairstylist and Aquage brand ambassador Laura Polko.

With that in mind, we searched the virtual shelves of beauty retailers and brands near and far to deliver you a list of thin hair shampoos that live up to the hype. Keep reading to find out what they are, and, while you’re at it, clear some room in your shower. There’s about to be a new shampoo in town.
