Nioxin System 4 Scalp & Hair Leave-In Treatment for Coloured Treated Hair with Progressed Thinning 100ml

Nioxin System 4 Scalp & Hair Leave-In Treatment for Coloured Treated Hair with Progressed Thinning (100ml) is a volumising leave-in scalp treatment for coloured treated hair with progressed thinning, the final step of the three-part Nioxin System 4 regimen. It treats colour-treated hair with noticeable, progressed thinning without rinsing, so thickening care keeps working between washes.

Professionally formulated with Nicotinate to strengthen the hair and increase its resilience, the treatment amplifies the texture and fullness of each strand and protects against breakage, creating a visibly thicker-looking result. Best results are achieved when all three steps of the System 4 regimen are used together.
