The Nioxin Shampoo for Colored and Thinning Hair functions as a professional-grade follicle-clearing system. It employs a high-load surfactant system to remove sebum while Peppermint Oil and Menthol provide a cooling sensation and support surface circulation. This combination is designed to enhance volume perception by lifting the hair at the root and removing heavy oils.
Active components include Salicylic Acid to chemically dissolve surface debris and prevent follicle clogging. While effective for oily scalps, the dual-sulfate complex requires manual lipid rebalancing with a lightweight conditioner to maintain hair shaft flexibility. Users may experience an initial shedding phase as the scalp adjusts to the increased surface stimulation and exfoliation.
