A Shopper’s Hair Grew from Their Chin to Their Waist Thanks to This Strengthening Shampoo

I’ve spent over a decade regularly applying heat to my natural hair. That’s why I’m constantly trying new products to heal my weakened strands, which lately consists of hair growth treatments. Kérastase’s Bain Extentioniste Shampoo is next on my list—a favorite of brand ambassador Emily Ratajkowski, though the brand is backed by Jennifer Aniston and Sydney Sweeney, also a brand ambassador. So naturally, I’m intrigued.

Kérastase’s Bain Extentioniste Shampoo is specifically made for damaged hair that’s slow to grow. It’s powered by the brand’s signature blend of amino acids that seals hair cuticles, leaving strands stronger. It works with taurine (another amino acid) that protects against external aggressors, leaving the scalp healthy and stimulated, which promotes hair growth. Even better, your tresses are left incredibly nourished thanks to ceramides, which seals in moisture to boost shine, softness, and elasticity in hair to prevent breakage. 

Many reviewers say the Bain Extentioniste Shampoo is effective for hair regrowth. “In six months, my hair grew so much and it grew thicker and healthier,” said a shopper who added that their strands “went from chin-length to waist-length.” Another customer shared that their heat-damaged hair is “finally growing past the horrible break-off point and it’s longer than it’s been in a very long time.” Other users rave that their hair is “growing faster,” so much so that it’s like they have a “new head of hair.”
