### ⭐⭐⭐⭐⭐ Product exactly as expected
*by A***1 on July 24, 2022*

I’ve been using this shampoo for a couple of years now and my hair salonist always tells me whatever shampoo I use is working well because I always have healthy new hair growth. I don’t use any product in my hair so it never feels weighed down like other reviews share.
