No thank you

All hair types are different but I did have higher expectations for this shampoo. It's very drying, tangles hair, and I had way more fall out while washing. I followed with the k18 leave in... which is a great product (that's for a different review). Hard pass on this shampoo.

Thick coarse hair miracle wash

Thick coarse hair that has lots of body and texture. Super picky with products and I spend the $$$. Only wash my hair 2x a week to maintain natural oils. This shampoo is amazing. Cleans and refreshes..I actually went 4 days between washes and hair still looked great. Im sold.
