The best shampoo and conditioner I've used in years

This is such a refreshing shampoo and conditioner. It has changed the texture of my hair for the better and my hair is no longer falling out the way it was! I won't use anything else from now on.

Very happy with this product

Usually I have to wash my hair daily to have any volume and not look greasy. With this bar shampoo, I am washing my hair every 4 days, and could probably go longer between. I’m very happy with this purchase. First time bar shampoo user.

Life changing!

WOW! I’ve tried bar shampoo and conditioner before. These are amazing. My hair has never felt so beautiful. It’s so shiny and soft. I have very fine hair and let me tell you, there’s something special about this hair products that make my hair look thicker and less frizzy.
