It’s okay
Item form: Tablet
Product says “deodorizes” so I thought it would leave a clean lemony smell, but it does not. Sometimes it foams other times it doesn’t but based on the description that’s normal?

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.
