NIOXIN System 4 Thickening Conditioner for Colored Dry Hair — Lightweight, Moisture-Balancing Strengthening

NIOXIN System 4 Scalp Therapy Conditioner is a lightweight, moisture-balancing conditioner formulated to strengthen colored hair with progressed thinning and leave it looking thicker and fuller.

Designed as the second step in the three-part NIOXIN regimen, this conditioner uses BioAMP technology to support hair resilience while helping retain moisture balance. It targets color-treated, dry hair with signs of advanced thinning by hydrating strands and fortifying the hair structure without weighing hair down. Regular use after the System 4 cleanser and followed by the Scalp & Hair Treatment helps create a healthier scalp environment that supports the appearance of density.

How does this conditioner help hair that has been colored and is thinning?

The formula focuses on strengthening fragile, processed strands and replenishing moisture lost during coloring. By amplifying each hair’s structure, the product helps hair appear fuller while protecting the vibrancy of color-treated hair.

• BioAMP technology restores moisture balance and reinforces hair resilience.
• Lightweight emollients hydrate without heavy buildup or limpness.
• Ingredients help reduce breakage and support the appearance of thicker hair.

Will it weigh my hair down or make it greasy?

No — the System 4 conditioner is formulated to be lightweight so it conditions the scalp and strands without adding excessive weight. It’s designed specifically for dry, color-treated hair that needs moisture plus density protection.

• Fast-rinsing texture that detangles without coating the hair.
• Balances moisture rather than saturating fibers with oil.
• Suited for daily use as part of the NIOXIN three-step routine.

How should I use it for best results?

Use this product as the second step after cleansing with NIOXIN System 4 Cleanser Shampoo. Apply from the scalp through the ends, leave on for 1–3 minutes, then rinse thoroughly; follow with the Scalp & Hair Treatment for a complete regimen.

• Apply to towel-dried hair after shampooing for consistent coverage.
• Massage into scalp to support a healthy scalp environment and even distribution.
• Use daily to see the intended improvement in hair fullness and manageability.

What visible improvements can I expect and how quickly?

Users often report improvement in the look and feel of hair within weeks when used correctly as part of the System 4 set. Clinical-style consumer feedback indicates many people noticed thicker-looking hair, increased density, and improved fullness.

• Perceptible thicker-looking hair with consistent, daily use.
• Helps reduce hair breakage to preserve existing strands and color.
