Nioxin System 4 Scalp & Hair Treatment is a specially designed treatment for noticeably thinning, fine, chemically-treated hair that delivers denser-looking hair while protecting the scalp and providing moisture balance to coloured hair.
This treatment contains antioxidants and botanicals that help to provide a refreshed scalp environment, and it is applied directly to the entire scalp, gently massaged in, and not rinsed out, although it may cause temporary redness to scalp skin after application.
