NIOXIN Scalp + Hair Thickening System 3 for Color-Treated Hair — Full-Size 3-Month Kit with Biotin & Niacinamide

NIOXIN Scalp + Hair Thickening System 3 is a three-step kit formulated to thicken and strengthen dry, color-treated hair with light thinning while protecting color.

This full-size, three-month supply combines a clarifying shampoo, a nourishing conditioner, and a leave-in scalp treatment to target the appearance of thinning and fragility in color-treated, damaged hair. Clinically and dermatologically tested, the system uses a blend of niacinamide, biotin and caffeine alongside botanicals and antioxidants to cleanse, hydrate and fortify each strand from root to tip. The regimen is designed to remove residue that can block follicles, restore moisture to weakened hair, and deliver leave-on nutrients that support a fuller-looking head of hair.

How does the three-step routine work to improve thinning hair?

The system uses sequential actions: a deep-cleansing shampoo to clear buildup, a conditioner to replenish moisture and protect against breakage, and a leave-in treatment to deliver continuous nourishment to the scalp and strands. Regular use helps hair appear thicker by improving strand resilience and volume. Results in many users are visible within 30 days when used as directed.

• Step 1: Scalp + Hair Shampoo — massages away sebum and environmental residues.
• Step 2: Scalp + Hair Conditioner — restores moisture balance and reduces breakage.
• Step 3: Scalp + Hair Thickening Treatment — shake, apply to scalp, and leave for ongoing nutrient delivery.

What key ingredients are included and what do they do?

The formulation centers on niacinamide, biotin and caffeine, each selected for supporting scalp and hair integrity without harsh sulfates or unnecessary fillers. Niacinamide helps condition the scalp, biotin supports keratin structure, and caffeine is included for its stimulating properties at the follicle level. Botanicals and antioxidants round out the formula to help protect color-treated hair from environmental stressors.

• Niacinamide — helps improve scalp condition and manage moisture.
• Biotin — contributes to stronger, more resilient strands.
• Caffeine — included to promote a refreshed scalp environment.
• Botanicals/antioxidants — protect color and reduce oxidative stress.

How should I use the system for best results?

Use the three products together as a routine for consistent, visible improvement. Start with a thorough one-minute shampoo massage, follow with a 1–3 minute conditioner application, then finish with the leave-in thickening treatment applied directly to the scalp. Consistency and correct application maximize the system’s performance over a 30-day period and beyond.

• Apply Scalp + Hair Shampoo to wet hair; massage for one minute and rinse.
• Distribute Scalp + Hair Conditioner evenly; leave for 1–3 minutes, then rinse.
• Shake the Thickening Treatment, apply to the entire scalp, massage in, and do not rinse.

Will this system affect my hair color or cause dryness?

The formulation is created for colored hair and includes ingredients intended to protect pigment while improving moisture balance. The conditioner and leave-in treatment work to restore hydration and reduce breakage that often follows chemical processing. Users with fragile or dry hair typically see improved texture and color protection when the kit is used as directed.

• Designed specifically for color-treated, dry or damaged hair with light thinning.
• Conditioner and leave-in treatment help maintain moisture and reduce breakage.
• Antioxidants in the formula support color longevity and hair health.

Who is this for: NIOXIN System 3 is aimed at people with color-treated hair that has become dry, fragile or shows light thinning. It suits anyone who wants a clinically tested, salon-grade three-step program to cleanse the scalp, strengthen strands and boost the appearance of fullness without sacrificing hair color. Ideal for those seeking a structured daily routine that addresses both scalp environment and strand resilience.
