NIOXIN Scalp + Hair Thickening System 3 Trial Kit – For Colored/Damaged Hair, Niacinamide & Biotin, 1-Month Supply

NIOXIN Scalp + Hair Thickening System 3 is a three-step daily regimen that cleanses, conditions and delivers a leave-in thickening treatment to help hair appear fuller and stronger on color-treated, dry or damaged hair with light thinning.

This trial-size kit from NIOXIN is formulated to address the specific needs of colored, brittle or thin-looking hair by combining a clarifying shampoo, a hydrating conditioner and a leave-on scalp treatment. Key actives such as niacinamide, biotin and caffeine are blended with antioxidants and botanicals to support a healthier scalp environment and improve each strand’s visual density. The set is dermatologically tested and designed for daily use to build more resilient-looking hair while helping to protect color vibrancy.

How does this system reduce the appearance of thinning?

The three-step protocol removes build-up, strengthens the hair shaft and deposits a lightweight treatment that adds body at the root. Together the products work to improve how hair lays and reflects light, creating the perception of fuller hair without weighing it down.

• Clarifying shampoo lifts sebum and residue that can flatten hair.
• Conditioner restores moisture balance to prevent breakage.
• Leave-in treatment targets the scalp to boost strand volume.
• Niacinamide and biotin help support hair fiber resilience.

What is the correct way to use each product for best results?

Follow the three steps every day for consistent results: cleanse, condition, then treat. Small differences in application — like massaging the shampoo for a minute and leaving the conditioner on briefly — ensure the scalp is prepared to receive the leave-in treatment.

• Apply shampoo to wet hair, massage scalp for one minute, then rinse thoroughly.
• Distribute conditioner from roots to ends, leave 1–3 minutes, then rinse.
• Shake the thickening treatment, apply directly to the entire scalp, massage in and do not rinse.
• Use daily for a month to evaluate visible improvement in fullness.

Will this kit affect color-treated hair or cause fading?

The formulas are designed to be safe for color-treated hair and include ingredients that help maintain color while addressing dryness and breakage. The gentle cleanser removes pollutants and styling residues without stripping the dye when used as directed.

• Shampoo clarifies without aggressive stripping of color.
• Conditioner helps seal the hair cuticle to preserve shine.
• Leave-in treatment contains UV-protecting botanicals for added defense.
• Daily use supports overall hair condition and color longevity.

Who is this for: This trial kit is intended for people with light thinning who have color-treated, dry, or chemically damaged hair and want a compact, daily routine to instantly enhance hair body and support scalp health. It suits anyone seeking a non-invasive way to improve the look of fullness while maintaining color, and it’s useful for first-time users who want a one-month introduction to NIOXIN’s three-step approach.
