NIOXIN System 2 Shampoo & Conditioner Prepack — 33.8 fl oz Pump Set, Thickening with Niacinamide & Biotin

Nioxin System 2 is a three-part professional scalp and hair thickening regimen—shampoo, conditioner and treatment—that targets natural or untreated hair with progressed thinning to visibly increase fullness and manageability.

Developed from three decades of thinning-hair research, this System 2 prepack combines a clarifying cleanser and a lightweight conditioner formulated to remove buildup, maintain scalp balance, and strengthen hair fiber for a fuller appearance. The set contains salon-sized pump bottles (33.8 fl oz) to simplify daily use and support a consistent routine.

How does System 2 prepare the scalp for thicker-looking hair?

The cleanser uses a professional-grade renewal technology to lift away excess sebum, environmental residue, and styling product build-up that can weigh hair down. Clearing the scalp creates a cleaner foundation so strands sit with more body and movement.

• Deep-cleansing shampoo removes oil and debris without stripping moisture.
• Targets residue that can make thinning hair appear flat.
• Prepares hair for the conditioner and follow-up scalp treatment.

What benefits does the System 2 conditioner provide for progressed thinning?

The lightweight conditioner restores moisture balance and reinforces hair structure to reduce visible breakage and loss of resilience. It’s designed to leave hair feeling soft and fuller without heavy residue.

• Amp technology helps strengthen individual strands for improved resilience.
• Conditions without weighing fine or thinning hair down.
• Enhances hair manageability and natural movement.

Which ingredients support scalp and hair health in this kit?

Key actives like niacinamide and biotin are included to support scalp circulation and hair structure while antioxidants and botanical agents help nourish the scalp environment. UV-protecting components help shield hair from photo-damage that can affect appearance.

• Niacinamide supports a balanced scalp environment.
• Biotin contributes to stronger-seeming hair fiber.
• Botanical extracts and antioxidants help soothe and protect.

How soon can I expect to notice changes, and how should I use the kit?

Visible improvement in fullness is often reported within weeks when the system is used consistently as a daily cleansing and conditioning routine. Use the shampoo to cleanse the scalp and hair, follow with the conditioner focusing on mid-lengths to ends, and incorporate the Scalp + Hair Thickening Treatment as directed for best results.

• Daily use yields the most consistent results.
• Apply shampoo to wet hair, rinse thoroughly, then condition.
• Finish with the included treatment product per package directions.

Who is this for: Nioxin System 2 is aimed at people with natural or untreated hair experiencing progressed thinning who want a professional-strength, easy-to-use daily system. It suits those seeking to reduce the appearance of thinning by removing scalp buildup, strengthening strands, and adding lightweight body—especially helpful for fine-to-medium textured hair that needs volume without heaviness.
