Nioxin System 4 Scalp + Hair Thickening Conditioner

Nioxin System 4 Scalp + Hair Thickening Conditioner is engineered for noticeably thinning, fine, and chemically treated hair. The Scalp Access Delivery System combines vitamins, botanicals, and SPF 15 sunscreen to cleanse away sebum and environmental buildup while protecting the scalp from sun damage. BioAMP technology with cystine amino acids strengthens each strand, increasing fullness and reducing breakage. Glyco-Shield protects chemically-treated hair with white tea extract, humectants, and peppermint oil, delivering lightweight conditioning that balances moisture without weighing hair down. This targeted formula addresses both scalp health and hair resilience for visibly thicker, stronger results.
