Overview
Nioxin System 2 is a scalp care shampoo formulated for natural hair with progressed thinning, designed to cleanse the scalp of buildup and excess sebum while supporting the appearance of thicker, fuller hair.
This is positioned as the cleansing step of a multi-part system rather than a stand-alone thickening product, so its scalp-clarifying role matters as much as any direct effect on the hair strands. The brand's own testing cites visible results at 30 days, but that reflects use within the full System 2 kit.

- Brand-cited testing: 85% saw thickening, 80% saw more density and fullness
- Formulated with botanicals, antioxidants, and UV protection
- Part of the Nioxin System 2 thickening kit
