NIOXIN System 2 Shampoo & Conditioner Prepack 33.8 fl oz — For Natural/Untreated Thinning Hair, Niacinamide & Biotin

Nioxin System 2 Prepack is a three-part scalp and hair thickening regimen formulated for natural or untreated hair with progressed thinning, delivering a cleaner scalp and visibly fuller-looking strands.

This professional kit combines a clarifying cleanser, a lightweight moisture-balancing conditioner, and targeted scalp treatment technologies to improve hair texture and appearance. Powered by Activ-Renewal technology, niacinamide, biotin, and botanical antioxidants, the System 2 regimen is designed to remove excess sebum and residue while supporting hair resilience and density appearance over time. The included pumps make salon-style dispensing convenient for home use and ensure consistent application across the 33.8 fl oz bottles.

How does System 2 improve the look of thinning natural hair?

Nioxin System 2 targets the scalp environment and hair fibers to help hair appear thicker and fuller. The cleanser removes buildup that can weigh strands down, while the conditioner supports moisture balance so hair keeps body without being heavy.

• Activ-Renewal technology clears sebum, fatty acids, and residue from the scalp and hair.
• Lightweight conditioner with Amp technology helps retain moisture and resilience.
• Formulated with niacinamide and biotin to support visible texture and thickness.

What results can I expect and how soon will I notice them?

Visible differences in texture and fullness are often reported within weeks, though individual results vary. Clinical feedback shows many users observed thicker-looking hair and increased density when the three-step routine was used consistently.

• Daily or regular use supports gradual improvements in hair appearance.
• Many users report noticeable changes in about 30 days with continued use.
• The regimen is designed to reduce breakage and help hair retain a fuller look.

How should I use the three products in the kit for best results?

Follow the three-step sequence: cleanse, condition, and apply any recommended leave-in treatment. Work each product through the roots to ends to ensure the scalp and hair receive the full benefit of the formulation.

• Step 1 — Cleanse with the derma-purifying shampoo to remove buildup.
• Step 2 — Apply the lightweight Scalp Therapy Conditioner to retain moisture and strengthen strands.
• Step 3 — Use the included scalp & hair thickening treatment or follow brand directions for targeted application.

Will this kit work with colored, chemically treated, or textured hair?

System 2 is formulated specifically for natural or untreated hair with progressed thinning; if your hair is colored or chemically altered, another Nioxin system may be a better match. For textured or chemically treated hair, consult the product guidance to choose the appropriate system for your hair’s condition.

• Designed primarily for natural, untreated hair types with progressed thinning.
• Color- or chemically-treated hair may require a different Nioxin system tailored to those needs.
• Check labels or consult a stylist to confirm compatibility with textured or treated hair.

Who is this for: Nioxin System 2 Prepack is intended for people with natural or untreated hair experiencing progressed thinning who want a salon-grade at-home routine to improve scalp cleanliness and the appearance of hair density. It suits users seeking a lightweight conditioner, scalp-focused cleansing, and convenient pump dispensers for larger bottles. If your hair is chemically processed or you need a system for earlier-stage thinning, review Nioxin’s other system options to find the best match.
