NIOXIN Night Density Rescue Serum — Overnight Hair Thickening Serum, 2.4 fl oz, Antioxidant Night Treatment

Nioxin Night Density Rescue Serum is an overnight leave-on treatment designed to promote the appearance of thicker, fuller-looking hair by protecting the scalp from oxidative stress.

Designed for nightly use, this intensive 2.4 fl oz serum uses Nioxydine(24) Technology — a targeted antioxidant complex — to help neutralize free radicals on the scalp surface that can contribute to weakened strands and hair fall. Dermatologically tested and formulated by Nioxin, a salon brand with decades of experience addressing thinning hair, the serum supports the scalp’s natural regenerative period while you sleep.

How does this serum work while I sleep?

The formula is intended as a leave-on night treatment so active antioxidants can work uninterrupted during the scalp’s nightly repair cycle. By targeting scalp-surface oxidation, the serum helps reduce environmental and metabolic stressors that can affect hair appearance. Results are reported as improved hair density appearance with continued nightly use.

• Leave-on formula for overnight absorption
• Nioxydine(24) antioxidant complex neutralizes free radicals
• Supports visible fuller-looking hair over time with regular use

How should I apply Night Density Rescue Serum?

Apply the serum directly to a dry or lightly damp scalp before bed, parting hair to expose the scalp and distribute product where needed. Massage gently to ensure even coverage, then style normally in the morning—no rinsing required. Consistent nightly application delivers the intended exposure time for the antioxidant system.

• Part hair to expose the scalp in thinning areas
• Apply recommended amount directly to scalp and massage in
• Leave on overnight; rinse or style as usual in the morning if desired

What results can I expect and when?

Users report a visible improvement in hair density appearance with continued use; individual results vary. The formula focuses on reducing hair fall associated with scalp surface oxidation and promoting the look of thicker hair over weeks to months. For best outcomes, integrate nightly use into your routine and combine with a compatible Nioxin system if desired.

• Targeted support for hair appearance, not a medical cure
• Gradual visual improvement with consistent nightly use
• Works alongside daily scalp-care routines and treatments

Is this suitable for my scalp and hair type?

Dermatologically tested and formulated for people noticing hair thinning or reduced density, the lightweight serum is generally suitable for most scalp types. It is intended as a cosmetic, leave-on treatment to complement other scalp and hair-care products. If you have specific scalp conditions or sensitivities, patch-test first or consult a professional.

• Lightweight, non-rinsing night serum
• Dermatologically tested for broad scalp compatibility
• Works with other Nioxin or professional scalp-care systems
