NIOXIN System 4 Shampoo & Conditioner Prepack — 33.8 fl oz Pumps | For Color-Treated, Damaged Hair with Progressed Thinning, Niaci

Nioxin System 4 Shampoo & Conditioner Prepack is a two-step professional regimen that cleanses, strengthens, and visibly thickens color-treated, dry, damaged hair experiencing progressed thinning.

This prepack combines Nioxin’s Cleanser and Scalp Therapy Conditioner formulated for color-treated, dry or damaged hair with progressed thinning. Enriched with niacinamide and biotin, the set is engineered to remove follicle-clogging residue, restore moisture balance, and increase hair resilience while maintaining color vibrancy. The kit comes in full-size 33.8 fl oz bottles with pumps included for easy dispensing and salon-style daily use.

How does System 4 improve hair thickness and manage thinning?

The formula targets weakened hair fibers and the scalp environment to create the appearance of fuller, thicker hair. Cleansing removes excess sebum and debris that can weigh hair down, while conditioning rebuilds moisture and body so strands look denser.

• Pro-Color Shield cleanses without stripping color.
• Niacinamide supports scalp microenvironment health.
• Biotin helps strengthen hair strands to reduce breakage.
• Lightweight conditioner adds density without heavy residue.

Will this duo protect my color-treated hair?

Yes — the System 4 Cleanser uses a pro-color approach to remove impurities while preserving salon color. The conditioner helps lock in moisture and smooth the cuticle to keep color looking brighter and reduce fading from daily wear.

• Formulated specifically for colored hair with progressed thinning.
• UV-protecting antioxidants help shield color from environmental stressors.
• Gentle cleansing reduces color-stripping surfactants.

What makes System 4 suitable for dry, damaged hair?

System 4 pairs a derma-purifying cleanser with an Amp technology conditioner designed to restore moisture balance and improve hair resilience. Together they address dryness, reduce breakage, and leave hair feeling softer and more manageable without weighing it down.

• Scalp therapy conditioner replenishes hydration while maintaining density.
• Fortifying ingredients improve elasticity to resist snapping.
• Lightweight formulation prevents buildup that can flatten fine or thinning hair.

How should I use these products for best results?

Use the Cleanser as the first step to remove oils and residue, then apply the Scalp Therapy Conditioner focusing on mid-lengths to ends to retain moisture and add thickness. For a complete routine, follow with targeted Nioxin treatments or styling products as needed.

• Apply Cleanser to wet hair, lather, and rinse thoroughly; repeat if needed.
• Distribute conditioner through lengths, leave for 1–2 minutes, then rinse.
• Use daily or as recommended by your stylist for visible improvement in weeks.

Who is this for: Nioxin System 4 Prepack is intended for people with color-treated, dry or damaged hair experiencing progressed thinning who want to cleanse the scalp, strengthen fragile strands, and enhance the appearance of density. It suits those seeking salon-quality, lightweight care that complements professional thinning-hair regimens, and it comes in convenient pump bottles for easy daily use.
