I have thick wavy hair that is constantly escaping hairdoes. I'm the girl with the halo of frizz.
Rather than use keratin products, I try to keep with gentler solutions, and this gets two thumbs up.
I've been using it for about two weeks and my hair is already tamer, moisturized, manageable. I use less styling products to keep it in line and it's shiny and soft. This goes on my favorites list.
