This is an excellent product. I've been using it for a few years now and it's amazing at controlling psoriasis on my scalp as well as cleaning hair. It also smells great :)
I am very pleased with the shampoo bars, so much so that my order of four bars was so I could use them as presents for family and friends.
I have been buying Moonhaven's shampoo bars for a few years now. I like that it is a plastic free purchase, and the shampoo bar with the cider vinegar conditioner leaves my hair more manageable than it has ever been.
