I love this shampoo along with the matching conditioner! I wish the bottles came in the bigger sizes. I have naturally wavy/curly thick hair that I usually straighten. This shampoo & the matching conditioner really help seal in moisture to help protect my hair from heat damage. I also LOVE the smell of this shampoo. This shampoo & conditioner always leave my hair frizz free, shiny, soft, protected, & smelling amazing. I will definitely buy this again once I run out.
