NIOXIN Scalp & Hair Thickening System 2 — Full-Size 3-Month Kit for Natural/Untreated Hair, 3-Step

This full-size, three-month kit pairs a deep-cleansing shampoo, a lightweight conditioner and a leave-in scalp and hair treatment to refresh the scalp, strengthen individual strands and help reduce hair breakage. Developed from a scalp-care approach, System 2 is engineered to remove buildup that can clog follicles while reinforcing hair resilience so each strand appears denser. Clinical and dermatological testing supports its use on natural, untreated hair with progressed thinning; many users see visible improvements in as little as 30 days.

How does System 2 improve hair thickness and density?

System 2 combines cleansing, conditioning and a leave-in treatment to create a fresher scalp environment and add body to individual hairs. The products work together to reduce residue that weighs hair down and to fortify strands so they are less prone to breakage.

• Step 1: Cleanser shampoo removes sebum and environmental residues that can clog follicles.
• Step 2: Lightweight conditioner restores moisture balance without flattening hair.
• Step 3: Leave-in scalp and hair treatment boosts volume and refreshes the scalp.
• Clinically observed improvements in thickness and fullness reported within 30 days by many users.

What specific scalp and hair concerns does this kit target?

System 2 is tailored to natural or untreated hair with progressed thinning; it concentrates on reducing breakage, enhancing strand texture and maintaining a healthy scalp surface. The formulation aims to clear follicle-clogging debris while delivering antioxidants and conditioning agents to the scalp and hair shaft.

• Removes follicle-clogging sebum, fatty acids and environmental buildup.
• Strengthens hair resilience to minimize breakage-related thinning.
• Delivers UV-protecting antioxidants and nourishing botanicals to the scalp.
• Leaves hair with increased body and a healthy-looking shine.

How do I use the three-step system for best results?

Follow the labeled three-step routine at each wash for consistent results. Regular application as directed helps maintain a cleaner scalp and supports the hair’s ability to appear fuller over time.

• Step 1: Massage the cleanser into wet hair and scalp, then rinse thoroughly.
• Step 2: Apply conditioner from scalp to ends, leave briefly if desired, then rinse.
• Step 3: Shake the leave-in treatment, apply to the scalp, and do not rinse out.
• Use as your daily or regular haircare regimen; pair with Nioxin Intensive Care products to complement results.

When will I notice a difference and are the results supported?

Many users report visible changes within the first month of consistent use. Results vary by individual, but clinical and consumer testing indicate high rates of perceived thickening, density and fullness on natural, untreated hair with progressed thinning.

• Reported outcomes: approximately 8 in 10 users noticed thicker, fuller-looking hair in 30 days.
• Designed and tested for scalp and hair conditions linked to progressed thinning on natural hair.
• Award recognition from professional stylist communities underscores its salon-focused formulation.

Who is this for: NIOXIN System 2 is designed for people with natural or untreated hair experiencing progressed thinning who want a salon-grade, scalp-focused regimen. It suits anyone aiming to reduce breakage, improve strand texture and create the look of increased hair density without heavy, coating products. If you follow a regular wash routine and want a three-step program that targets both scalp cleanliness and strand fortification, this kit is formulated for that purpose.
