If my hair is relaxed, how do I grow an afro?

no, once it is relaxed, either curly or straight, it will never be the same again. Your hair will loose its natural texture so if you want all your naturalness back, you gotta chop it off. I suggest you just stop with the chemicals, and try to grow your hair out before you cut it. You don't want to have a short bush on your head, so why not chop it off when its already full?
