Great Product for Hard Water
Style: Shampoo
We have hard water and just after a week of using this I can already tell a difference, not only that but I've been using it on my upper arms, shoulders and neck and my keratosis pilaris is clearing up and my skin is smooth. Great product, happy I found it.
