If you’re seeking longer, stronger, thicker-looking hair, chances are you’ve found yourself deeply entrenched in Amazon’s hair growth product offerings.

Kitsch Rice Water Shampoo Bar

$14 $11 at Amazon

While somewhat unconventional in its format, this solid shampoo bar is a favorite among shoppers—more than 7,000 of whom have given it a perfect five-star rating. One reviewer reports “fuller and shinier” hair after one month of use, while another says their “hair is growing back better than ever, with less breakage and fallout.” True to its title, the formula features rice water, an nutrient-dense ingredient that promotes stronger strands and new growth.

Divi Hair Scalp Serum 

$48 $38 at Amazon

This lightweight, non-greasy serum touts some of the most potent, science-backed hair growth ingredients. Rosemary, peppermint, and caffeine, for instance, improve scalp circulation;  consequently, hair follicles receive the nutrients necessary for healthier, faster growth.

First Botany Biotin Hair Growth Shampoo and Conditioner 

$25 $22 at Amazon

I’m a proponent of integrating hair growth products into a shower routine; after all, using shampoo spiked with growth-spurring ingredients nixes the need to add an extra step via a serum or oil. Complete with a corresponding conditioner, this in-shower duo relies on keratin to strengthen weak strands—and, consequently, prevent breakage. Moreover, shoppers reported visible new growth, particularly around the hairline.

For stronger, longer, fuller hair, snap up Amazon’s shopper-loved growth solutions. Plus, snag similar formulas at Amazon, below, while they’re still on sale ahead of Prime Big Deal Days.
