Nioxin System #4 Full Size Kit

If your hair is coloured, damaged and thinning, it needs more than a thicker-looking hairstyle. This three-step system is designed to gently cleanse, strengthen vulnerable strands and support a healthier scalp, helping hair look fuller while protecting your colour.

Clinically and dermatologically tested, System Kit 4 is made for progressed thinning in dry, damaged or colour-treated hair. In a clinical study, 8 out of 10 users noticed thicker, fuller-looking hair after 30 days.
