Anyone successfully manage to get rid of this stuff out your hair? Had mine done two months ago and I want my curls back. How do I get them back? It was the string keratin that you can wash your hair immediately afterwards. I've tried swimming and sulphate shampoo and it's only getting a little bit frizzy at the root? I have had many keratin treatment over the years, this makes my hair so dry when wet, like straw.
