I have used this product. It was horrible for me. It changed my hair color and made it all brassy, and I don't know why, but keratin just never does what it claims it will on my hair. Yuck!
Very coarse, thick, porous 3B. My biggest challenge is SOFTNESS and SHINE.

Current shampoo: Biosilk w/ added vitamin E
Current conditioner: Lush Okra
Leave-ins: Shea Moisture Curl Enhancing Smoothie, KCCC
CG didn't work for me. Oils don't work for me. Trying hard to learn how to love my hair. Read my blog.
