NIOXIN System 4 Scalp + Hair Thickening Treatment is a leave-in serum formulated to nourish the scalp and visibly increase hair diameter for color-treated or damaged hair with progressed thinning.
This professional-grade finish step completes the three-part NIOXIN System 4 regimen to help refresh the scalp and strengthen fragile strands. It combines antioxidants, botanicals and UV-protective ingredients in a lightweight delivery that targets the scalp environment while adding thickness and manageability to colored hair that has experienced thinning and damage.
The serum is designed to increase individual strand diameter and enhance the appearance of fullness without adding heavy residue. Applied to the scalp and lengths, it supports hair structure and helps reduce the visual impact of breakage and fragility.
Users typically notice improved fullness and thickness in the weeks after consistent use as part of the complete System 4 routine. NIOXIN reports consumer-observed increases in thickness, density and fullness when the treatment is used with the matching cleanser and conditioner.
Use this Scalp + Hair Thickening Treatment as the final step after cleansing with the System 4 Cleanser Shampoo and conditioning with the System 4 Scalp Therapy Conditioner. Apply directly to the scalp and hair while styling or as a leave-in refresher to target thinning areas and damaged lengths.
This treatment is tailored for colored, damaged hair with progressed thinning, focusing on scalp balance and strand protection. The formula integrates scalp-delivery technology plus UV-protective components to help defend color-treated fiber and support a healthier scalp surface.
Who is this for? NIOXIN System 4 Scalp + Hair Thickening Treatment is aimed at people with color-treated, chemically or heat-damaged hair who are experiencing progressed thinning and want a salon-strength leave-in to bolster hair diameter and scalp condition. It works best when paired with the full System 4 cleanser and conditioner and is suitable for regular use by those seeking a thicker, fuller look while protecting color-treated strands.
