Query: Pretty Sweet!

I put this on when my hair is still wet and I can literally feel my hair RELAX. I have thick curly/waves that takes me awhile to control and straighten. I even put it on one day then decided to wear my hair curly and it didn't even curl. With the heat from a hair dryer and a round brush I can get my hair straight without a flat iron!
