Hello. I'm trying to decide if I should try a keratin treatment. I have extremely curly, frizzy hair that is very dry and damaged in the back of my head. I just let it dry naturally and use Deva products on it. I hate my hair!! I would love to have loose silky curls instead of tight frizzy curls. Do you think keratin might be a solution? Before finding this website today, I wasn't even aware that there were so many different types. Any advice would be greatly appreciated. Don't know if it matters, but I am a 49 year old caucasian female.
