NIOXIN System 3 Shampoo & Conditioner Prepack 33.8 fl oz — For Color-Treated, Light Thinning with Biotin & Niacinamide

Nioxin System 3 is a three-step scalp and hair regimen formulated to visibly boost fullness and strengthen dry, color-treated hair with light thinning.

This prepacked professional kit pairs a clarifying shampoo, moisture-restoring conditioner and a leave-in thickening treatment to address breakage, buildup and limp strands. The formula blend includes niacinamide, biotin and caffeine to support a healthier scalp environment while helping hair look denser and more manageable. The set is clinically and dermatologically tested and comes with pump dispensers for easy daily use.

How does this kit improve hair thickness without affecting color?

The System 3 trio is designed to remove residue that can weigh hair down while preserving color-treated strands. Cleansing clears follicle-clogging buildup; conditioning restores moisture balance; and the leave-in treatment adds lift and resilience to each fiber. Together they aim to enhance the appearance of fullness without stripping pigment.

• Scalp + Hair Shampoo: removes excess sebum and environmental residues.
• Scalp + Hair Conditioner: replenishes moisture and reduces breakage.
• Scalp + Hair Thickening Treatment: provides leave-in volume and protection.
• Formulated to be color-safe while improving strand body.

What active ingredients support scalp and strand strength?

This kit combines targeted actives and botanicals aimed at improving the scalp environment and reinforcing hair structure. Niacinamide helps support scalp health, while biotin contributes to visible strand strength. Caffeine is included to energize the scalp area, and antioxidants help protect hair from daily stressors.

• Niacinamide: supports healthier-looking scalp condition.
• Biotin: helps improve hair resilience and manageability.
• Caffeine: included for scalp-stimulating properties in topical use.
• Antioxidants and botanicals: protect from environmental stress.

How do I use each product for best results?

Use the three steps as a daily or regular routine: cleanse, condition and finish with the leave-in treatment. Massage the shampoo into wet hair for about one minute before rinsing. Apply conditioner to hair and scalp for 1–3 minutes then rinse, and shake the treatment well before applying directly to the scalp; do not rinse it out.

• Shampoo: apply to wet hair, massage for one minute, rinse thoroughly.
• Conditioner: leave on 1–3 minutes, distribute evenly, then rinse.
• Thickening Treatment: shake well, apply to scalp, massage, leave in.
• Pumps included for controlled dispensing and convenient daily use.

When will I notice changes and are there safety considerations?

Individual results vary, but many users report improved fullness and manageability within weeks of consistent use. Because this is a topical cosmetic system, avoid contact with eyes and discontinue use if irritation occurs. Consult a professional for personalized advice if you have specific scalp conditions.

• Visible improvements reported with regular use over weeks.
• Avoid eye contact and rinse if product enters eyes.
• Stop use if irritation or allergic reaction develops.
• Safe for color-treated hair when used as directed.

Who is this for: Nioxin System 3 is suited for people with dry, damaged, color-treated hair experiencing light thinning who want a salon-grade, daily regimen to lift strands and improve scalp condition. It’s ideal for anyone seeking a routine that cleanses away buildup, restores moisture, and leaves a lightweight, thicker-looking finish without compromising hair color.
