Melaleuca Herbal shampoo is the best shampoo that my family has ever used. My husband was especially bothered by dry scalp and a type of scalp condition that made his scalp very sore and uncomfortable. I got the Melaleuca herbal shampoo for him and it cleared up the condition completely and he has had no further problems with it in the five plus years that he has been using this shampoo. The contents include a special type of tea tree oil and I think that is the ingredient that has helped him so much. Also it is not only a shampoo but also a hair conditioner that leaves your hair silky and manageable. I like the very fresh and natural smell of this shampoo very much also. The only problem at all is that in order to buy this at a special price you have to sign up to be a member and order a certain amount of products every month. They have a lot of good products but sometimes this gets pretty expensive. However that takes nothing away from how great this shampoo is.
