Awesome shampoo I’ve tried all joico shampoo and conditioners this was the best. No frizz just soft healthy hair.

Rated 5 out of 5

I have natural 3 a/b curls. I wash or wet my hair every day and I’ve used tons of products trying to get shiny, soft, defined curls with no frizz. I love all Joico products but this entire Defy Damage line is terrific. The protective masque is everything.
