I have very thick hair which has a bit of a kink and is frizzy if I just leave it. I always straighten it and it looks nice but doesn't stay like that for long. I only wash it once a week and after sleeping on it or execising it goes horrible and frizzy. I definately don't have time to straighten it evey day. I'm thinking about seeing if it's actually wavy but know I need products for this and don't know where to start. There are so many videos out there! Has anyone got any recommendations? Also what do you do about brushing/combing your hair if you don't wash it every day?
