Aloveen Oatmeal Shampoo is a gentle hypoallergenic shampoo that may be used on both cats and dogs. This shampoo can be used on both pets with normal skin as well as those who suffer from dry and itchy skin. It works in two important ways; Aloveen firstly removes the allergens from the skin with the gentle foaming shampoo base, and then soothes the skin with both the superfine colloidal oatmeal particles and aloe vera.
