Nioxin System 4 is specially designed for noticeably thinning, fine, chemically-treated hair. It delivers denser-looking hair while protecting the scalp and providing moisture balance to color-treated hair.

This product is a lightweight cleanser and conditioner that helps turn thinning hair into thicker, more luxurious locks. This product helps to remove residual leftovers from repeated washing and everyday dirt accumulation that end up clogging the hair follicle from the scalp skin and hair. The xcleanser also helps control the moisture balance of the hair and gives it a resilient shine.
