I have been reading about the harmful effects of shampoo on your hair and scalp. I also read that many people just stop using shampoo (they refer to it as no-poo) and comment on how their hair is in better condition. No-shampoo doesn't mean no-washing. You rinse your hair and either massage your scalp with your fingertips or use a plastic brush to "massage" your scalp. I am on day 2 with no poo. So far so good. I will keep you posted.
