NIOXIN Scalp & Hair Thickening Conditioner System 2 — 33.8 fl oz for Natural/Untreated Hair with Niacinamide & Biotin

NIOXIN System 2 Scalp + Hair Thickening Conditioner is a lightweight, salon-grade conditioner formulated to strengthen natural hair with progressed thinning while balancing scalp moisture.

This professional conditioner, part of NIOXIN's three-step System 2 regimen, combines niacinamide, biotin, and the brand's BioAMP technology to fortify hair structure and help hair appear fuller without weighing it down. Designed for natural or untreated hair experiencing progressed thinning, the formula targets scalp health and hair resilience so daily styling and environmental stressors have less visible impact.

How does this conditioner help hair feel thicker and stronger?

The conditioner uses BioAMP technology plus strengthening nutrients to reinforce each strand and improve hair body. It smooths cuticles for better strand alignment and reduces the likelihood of breakage that can make hair look sparse.

• BioAMP technology increases hair structure and fullness.
• Niacinamide and biotin support a resilient hair fiber.
• Lightweight moisturizers add slip and reduce breakage during styling.

Can it improve the condition of my scalp and how should I use it?

The formula is crafted to support a healthier scalp environment by removing residue and helping retain moisture balance. For best results, apply after cleansing with the System 2 cleanser, distribute across the scalp and hair, leave on for 1–3 minutes, then rinse thoroughly.

• Use daily after NIOXIN System 2 Cleanser Shampoo.
• Massage gently into scalp to promote even coverage.
• Rinse after 1–3 minutes to avoid product buildup.

Will this weigh my hair down or alter my style?

System 2 Conditioner is formulated to be lightweight so it adds moisture and resilience without heavy residue that can flatten natural hair. It aims to preserve movement and volume while improving manageability and detangling.

• Light, non-greasy texture suitable for fine-to-medium natural hair.
• Helps detangle and reduce styling time without stiffness.
• Compatible with daily styling products and heat tools when used as directed.

What results can I expect and how soon?

Users often report improved fullness and strength with consistent use as part of the System 2 regimen. While individual responses vary, visible improvements in hair body and reduced breakage are commonly noticed within a month of regular use.

• Designed for visible fullness and thicker feeling hair with routine use.
• Helps reduce the appearance of thinning by strengthening hair fibers.
• Works best when paired with NIOXIN System 2 Shampoo and Scalp & Hair Treatment.

Who this product is for: NIOXIN System 2 Scalp + Hair Thickening Conditioner is intended for people with natural or untreated hair experiencing progressed thinning who want a professional-grade conditioner that promotes scalp health, strengthens hair structure, and enhances the look of fullness. It's suitable for daily use within the System 2 regimen and for those seeking salon-strength support without heavy buildup.
