Promising review: "I love this product! My hair is long, thick, curly, color-treated, and very, very dry. I live in Florida, so I fight constant frizz year-round. I've used this hair mask twice. My hair is now frizz-free, shiny, healthy, and looks amazing. I wouldn't believe that after just two applications over two weeks would make such a significant difference, but they did. I've tried many, many hair products and nothing has produced these results before. I wash my hair, then dry it, then apply the conditioner. I put on a shower cap, wrap my head in a towel, and let it soak in for 30-45 minutes. My hair sucks it in." —Connie D
