Nioxin System 1 treatment is for anyone with natural (uncolored, unbleached) hair of any type with slight thinning (you notice the hair falling out more, but you can't easily see the scalp when looking in a mirror). It increases the diameter of each hair strand, adding volume and moisturizing the hair and scalp for thicker, fuller, stronger hair.

Apply to damp, towel-dried hair and scalp immediately after showering with System Kit shampoo and conditioner. NOTE: if using 3D Intensive Hair Booster, apply Hair Booster before scalp and hair treatment.
