I thought that Keratin treatments were meant for my hair type??? I thought the whole purpose was to make frizzy hair smooth and easy to manage. I just don't want my hair straight....I still want curl, just a soft curl. I have been using Deva products for several years now....No-poo, One Condition and Arc Angel. And I have my hair cut by a certified CG stylist. And I never blow it dry or straighten it, yet it is dry and damaged in the back. Suggestions?
