I've listened to (or read) the discussion go back and forth about surge. I am so confused. I think I'm ready to try it but I'm afraid of some of the side effects I've ready about. Are those complaints about burning scalps and breaking hair the norm, or is surge a generally safe product? I need some feedback on this one. I don't know what to do. Note: my hair is relaxed and about two inches from shoulder length. I think I have 4a/b type hair, but the more I deal with my hair, the less I'm sure about that.
