NIOXIN System 3 Hair Thickening Shampoo & Conditioner Kit — For Colored/Damaged Hair, 33.8 fl oz

NIOXIN System 3 is a three-step scalp and hair thickening kit formulated to strengthen, nourish and visibly increase the appearance of fullness in dry, damaged, color-treated hair with light thinning.

This professional three-part regimen combines a clarifying shampoo, moisture-preserving conditioner and leave-in thickening treatment to address weakened strands and scalp buildup. The formulas use niacinamide, biotin and caffeine along with botanicals and antioxidants to help fortify hair fibers, protect color and create a cleaner foundation at the scalp for healthier-looking hair. The pack includes pump dispensers for easy daily use and contains full-size 33.8 fl oz bottles ideal for at-home maintenance.

How does the System 3 routine rebuild hair strength?

The kit targets both the scalp environment and individual strands to reduce breakage and improve resilience. The shampoo removes residue that can interfere with follicle performance, the conditioner rebalances moisture, and the leave-in treatment delivers nutrients and protective ingredients to each strand’s base.

• Scalp + Hair Shampoo gently cleanses away sebum and environmental buildup.
• Scalp + Hair Conditioner restores moisture without weighing hair down.
• Scalp + Hair Thickening Treatment deposits niacinamide, biotin and antioxidants to strengthen roots and shaft.
• Pump bottles help dispense consistent doses for routine use.

Will this kit protect color-treated hair and reduce fading?

System 3 is formulated to be safe for color-treated hair while helping preserve vibrancy. Cleansers are designed to remove damaging residues without stripping color, and antioxidants plus UV-protecting ingredients help shield the hair surface from environmental stressors that accelerate fading.

• Color-safe cleansing that avoids harsh sulfates that can strip dye.
• Conditioner helps seal the cuticle to maintain shine and hue.
• Leave-in treatment contains antioxidants and UV protective elements to defend against color loss.

How should I use each step for best results?

Follow the three-step sequence every wash day for consistent results. Use the shampoo first to cleanse the scalp, apply the conditioner to replenish moisture, and finish with the leave-in treatment applied directly to the scalp for ongoing nourishment and thicker-looking hair.

• Apply shampoo to wet hair, massage into the scalp for about one minute, then rinse thoroughly.
• Distribute conditioner evenly, leave for 1–3 minutes, then rinse to avoid buildup.
• Shake the thickening treatment, apply to the entire scalp, massage gently and do not rinse out.

What results can I expect and how quickly?

Individual outcomes vary, but clinical and dermatological testing reported visible improvements in fullness for many users within a month. Improvements focus on reduced breakage, a cleaner scalp environment and an immediate boost to strand volume from the leave-in treatment.

• Noticeably fuller look reported by many users in approximately 30 days.
• Reduced appearance of thinning through decreased breakage and thicker strand profile.
• Ongoing use supports scalp health and helps maintain color vibrancy.
