Nioxin System 2 Shampoo/Conditioner Kit pairs the System 2 Cleanser Shampoo with the System 2 Scalp Therapy Conditioner - the two-piece version of Nioxin's System 2 regimen, formulated for natural, non-color-treated hair that has reached a more progressed, visibly advanced stage of thinning. That's a specific profile within Nioxin's numbered system line: System 1 targets natural hair with only light or early thinning, System 2 targets natural hair once thinning has progressed further, and Systems 3/4 are built instead for color-treated hair.
The shampoo is a sulfate-based cleanser meant to clear the scalp of excess oil and product buildup, while the conditioner is a lightweight, root-to-end formula designed not to weigh hair down or add the kind of heavy coating that can make thinning hair look flatter. Both are built around niacinamide, biotin, and peppermint/wild mint oils intended to support scalp comfort and hair body, alongside a set of plant extracts including green tea, nettle, saw palmetto, hops, and grapefruit peel.
This particular kit is the two-piece shampoo-and-conditioner set; it does not include the separate leave-in Scalp & Hair Thickening Treatment that Nioxin also sells as part of its full three-part System 2 lineup. For daily use, the two products are meant to be used together as a wash-and-condition routine rather than a single-step product.
