I have 2b hair and my waves don't start at my crown... they begin a couple of inches down. I can go a year before having to touch up my roots. I TRed my hair in December and it still looks and feels wonderful. Based on what other folks are saying, I would only recommend this procedure for folks who have waves versus curls. I can't imagine retouching my hair five times a year... holy cow!
2a/b. I love AOHR!
