NIOXIN Night Density Rescue Serum — Overnight hair thickening serum, 2.4 fl oz, antioxidant Nioxydine for fuller-looking hair

This intensive nighttime serum from Nioxin uses Nioxydine(24) Technology — a blend of antioxidants — to target scalp surface oxidation while you sleep. Dermatologically tested and developed by the salon brand with decades of experience in thinning hair, the formula is designed to be left in overnight without rinsing. It aims to support a healthier-looking scalp environment that can help hair look denser over time when used as part of a consistent routine.

How does Night Density Rescue work while I sleep?

The serum leverages antioxidant-rich Nioxydine(24) Technology to neutralize free radicals on the scalp surface, which are associated with surface oxidation. By applying the lightweight leave-on formula at night, it works continuously during the body’s natural repair period to support a more resilient scalp environment.

• Applies easily as a lightweight overnight leave-on treatment.
• Targets scalp surface oxidation with antioxidant actives.
• Designed for continuous nocturnal activity to complement daily care.

When will I notice thicker-looking hair?

Results vary by individual, but clinical testing reported visible improvements in hair density with continued use over several weeks to months. Consistent nightly application and pairing with a suitable scalp care system helps maximize visual improvements in fullness and coverage.

• Intended for nightly use as part of a regular routine.
• Clinical timelines commonly span multiple weeks for visible change.
• Best combined with Nioxin cleansing and scalp care products.

Is this safe for my scalp and hair type?

Nioxin Night Density Rescue is dermatologically tested and formulated for leave-on use on the scalp. The lightweight, non-greasy texture is designed to work with a range of hair types; however, those with specific scalp conditions or sensitivities should patch-test or consult a professional prior to use.

• Dermatologically tested formula for scalp application.
• Non-rinse, lightweight texture suitable for overnight wear.
• Patch-test recommended for very sensitive scalps or reactive skin.

How should I incorporate this serum into my routine?

Apply the serum to the scalp at night after cleansing and styling, then leave it in until morning—no rinse required. For best results, use consistently and consider pairing it with Nioxin shampoos and conditioners designed for thinning hair to support overall scalp health.

• Use nightly on dry or towel-dried scalp before bed.
• Massage into the scalp for even distribution and absorption.
• Combine with Nioxin scalp care system for a comprehensive approach.

Who is this for? Nioxin Night Density Rescue Serum is ideal for people concerned with hair that appears thinning or lacking density and who want a targeted overnight leave-on treatment. It suits users seeking salon-developed scalp care that focuses on protecting the scalp surface from oxidative stress, and those looking to integrate an antioxidant-rich step into their hair-thinning prevention regimen. If you have an active scalp condition, consult your dermatologist before use.
