System 1 amplifies hair texture and protects hair against breakage. System 1 is specially formulated as a hair thickening treatment, delivering denser-looking hair. It reduces hair loss due to breakage and strengthens the hair, while refreshing the scalp and delivering a healthy shine to natural hair with light thinning.

Nioxin’s Scalp & Hair Treatment System 5 for chemically treated hair with light thinning is the final step of a three part Nioxin regimen, specially formulated to refresh the scalp and increase hair volume. The volumizing Nioxin leave-on treatment helps provide thicker looking hair by increasing the fullness of each hair strand.

Nioxin System Kit 6 for thinning chemically-treated, bleached, permed or straightened hair delivers thicker, fuller hair with smooth control by removing follicle-clogging sebum, fatty acids and environmental residues, while restoring the moisture level and providing color protection. Gently massage into hair and scalp.
