#1 fav hair product

My hair feels almost like a new and improved texture after using this - silky smooth and virtually frizz free. Feels like I’ve gotten a fresh Cezanne frizz treatment when I use this. #1 fav hair product

Amazing just pricy

I love this product it really works for my hair type great at detangling and as a heat protectant. I do have extremely long thick hair but that’s part of the reason I am not giving it 5 stars for the amount of product I do feel it is too expensive expensive
