I haven't permed in about five months and I am interested in texturizing my hair to loosen up the curl pattern a little. I've been calling around to various salons and I can't find anyone who applies texturizers so I think I'm stuck with applying one myself. Does anyone have any advice on what brand I should get? How long should I keep it in? How often should I do a touch up?...etc. I don't know as much as I should about them but I really want to try one out.
