NIOXIN Scalp + Hair Thickening System 2 Trial Size — 1 Month Kit for Natural Hair with Niacinamide & Biotin

Nioxin System 2 is a three-step scalp and hair thickening kit formulated to strengthen strands and create denser-looking natural hair with progressed thinning.

This trial-size, one-month supply combines a clarifying cleanser, a lightweight conditioner and a leave-in scalp treatment to reduce breakage, refresh the scalp and visibly increase hair fullness. Backed by salon research and clinical testing, System 2 targets natural, untreated hair with progressed thinning by removing follicle-clogging residues, restoring moisture balance and improving strand resilience.

How does this kit improve the look and feel of thinning natural hair?

The formula set works together to clear buildup, fortify each strand and give the appearance of thicker hair without heavy residue. Regular use supports a healthier scalp surface and fuller-looking hair shaft definition.

• Step 1 cleanser removes sebum, fatty acids and environmental debris.
• Step 2 conditioner restores control and lightweight moisture.
• Step 3 leave-in treatment boosts volume and refreshes the scalp.
• Niacinamide and biotin help support scalp and strand resilience.

What results can I expect in 30 days?

Users commonly report visible thickening and improved density within a month when used as directed. While individual outcomes vary, clinical data and consumer feedback show increased fullness and reduced signs of breakage for many users.

• Clinically observed thicker-looking hair in 30 days for many participants.
• High percentage of consumers noticed more density and fullness.
• Reduces hair loss due to breakage by strengthening strands.
• Provides healthier shine and refreshed scalp appearance.

How do I use the three-step System 2 routine properly?

Follow the numbered steps each wash day for best performance: cleanse, condition and apply the leave-in treatment. The leave-in is not rinsed so it continues to act on the scalp between washes.

• Step 1: Massage cleanser into scalp and hair, then rinse thoroughly.
• Step 2: Apply conditioner from scalp to ends, then rinse to maintain lightweight control.
• Step 3: Shake the scalp treatment and apply it directly to the scalp; do not rinse.
• Use consistently—daily or as recommended—to maintain scalp health and strand resilience.

Can I combine System 2 with other Nioxin products?

Yes. System 2 pairs well with Nioxin Intensive Care products for targeted needs like extra moisture or strengthened ends. Choose complementary treatments based on your hair goals while keeping the core three-step regimen for best results.

• Use intensive serums on dry or damaged lengths as needed.
• Subscribe and save options are available to maintain consistent use.
• Follow product instructions to avoid overlapping active treatments.

Who is this for: Nioxin System 2 is aimed at people with natural, untreated hair experiencing progressed thinning who want a salon-backed, three-step approach to improve scalp condition and the visual density of their hair. It’s ideal for those seeking a lightweight routine that reduces breakage, refreshes the scalp and produces fuller-looking strands without heavy styling buildup.
