An effective and innovative leave-in treatment, the NIOXIN System 4 Scalp Treatment for noticeably thinning, fine, chemically-treated hair is the last step in your NIOXIN three step system. Specifically designed to help densify normal to fine, coloured hair types, it contains antioxidants and botanicals that work in synergy to maintain a refreshed scalp environment.

Formulated with BioAMP® and Scalp Access Delivery System® technologies, the treatment increases the appearance of density whilst strengthening every strand and reducing hair loss; its combination of Peppermint Oil and White Tea extract give the scalp a super fresh feel. Also contains added SPF 15 for protection against damaging sun rays. Expect glossy, denser-looking hair with a rejuvenated and stimulated scalp.
