NIOXIN System 3 Scalp + Hair Shampoo for Color-Treated Damaged Hair — 10.1 fl oz, Niacinamide & Biotin for Fuller-Looking Hair

Nioxin System 3 Scalp + Hair Shampoo is a color-safe cleansing formula that gently frees the scalp and strands of residue while moisturizing damaged hair to create the appearance of thicker, fuller hair.

Built for dry, chemically treated hair showing light thinning, this professional-grade cleanser is the first step in Nioxin’s three-part System 3 regimen. Formulated with niacinamide, biotin precursors, European botanicals and humectants, the shampoo removes follicle-clogging sebum and environmental build-up while helping restore moisture balance and manageability. It prepares the scalp and hair to receive the follow-up conditioner and treatment that amplify hair structure and improve overall look and feel.

How does this shampoo improve the look of thinning, color-treated hair?

The formula targets surface impurities and excess oils that can make fine or thinning hair look limp and sparse. By cleansing away residues and adding moisture where hair is dry or damaged, it helps strands sit with more body and texture, improving visual density.

• Removes sebum, fatty acids and styling residues that weigh hair down
• Humectants moisturize dry, chemically treated fibers
• Niacinamide and protein-building ingredients support strand resilience
• Prepares hair for System 3 conditioner and treatment for layered benefits

Is this shampoo safe for colored or chemically treated hair?

Yes — System 3 is formulated to protect color while addressing dryness and light thinning. The cleanser is gentle enough for salon-treated hair and created to maintain vibrancy while improving scalp condition and strand fullness.

• Color-safe surfactant system designed for treated hair
• Moisturizing botanicals reduce tightness and dryness

How should I use Nioxin System 3 for best results?

Use System 3 daily as the cleansing step in the three-part regimen. Apply to wet hair, gently massage into the scalp and hair for about a minute, then rinse thoroughly before following with the matching System 3 conditioner and scalp treatment.

• Apply to wet hair and scalp, massage 1 minute, then rinse
