After taking a bath tonight, I didn't do anything to my hair. Usually I take a minute to comb it and it has been drying pretty straight due to the keratin treatment.
Tonight, I didn't do a thing to it and let me tell you, the curls are still there. They are a little more relaxed and more all over, not just straight on top and curly on the bottom how it was before, but it's really easy to make straight, with a brush and a hairdryer, in minutes, something I couldn't do before because my hair was just so stubborn.
I just don't know WHERE my hair gets it from.
