Nioxin System 1 Scalp Therapy Conditioner — 10.1 fl oz, lightweight thickening with niacinamide & biotin for natural hair

Nioxin System 1 Scalp Therapy Conditioner is a lightweight, density-enhancing conditioner formulated to strengthen natural hair with light thinning while helping balance scalp moisture.

Nioxin System 1 Conditioner is the second step in Nioxin's three-part regimen, designed for natural or untreated hair experiencing light thinning. The formula combines BioAMP technology with supportive ingredients such as niacinamide and biotin to help fortify hair fibers, reduce breakage, and maintain scalp balance. It rinses clean and leaves hair manageable without heaviness, making it suited for fine textures that need structure and resilience.

How does this conditioner boost hair structure without weighing hair down?

The System 1 conditioner uses a lightweight conditioning base plus BioAMP technology to strengthen each strand and improve hair body. Instead of heavy oils, it focuses on moisture balance and resilience so fine hair keeps lift and movement after rinsing.

• BioAMP technology to amplify hair structure and manageability.
• Lightweight emollients that hydrate without flattening roots.
• Formulated for fine, natural hair prone to light thinning.
• Rinses clean to preserve volume and reduce residue buildup.
