I have psoriasis in my scalp and have tried several over-the-counter products that claim to relieve itching and flaking, but nothing has worked for me as well as Malibu C Scalp Wellness Shampoo and Conditioner. The shampoo leaves my hair shiny and a very small amount of Scalp Wellness Conditioner leaves my hair manageable, but not oily-feeling. The itching and flaking are greatly reduced. I would recommend these products to anyone.
