Home / Hair Loss Products / Shampoos / Nioxin Shampoo Nioxin Shampoo Nioxin typically comes in a three part kit. The 3 parts of each NIOXIN system – cleanse, optimize, treat – work together to help nourish the scalp and give you thicker, denser-looking hair. It works due to its key ingredient ketoconazole, but can also cause negative effects to your hair with its use of parabens.
