NIOXIN Age Defense Anti-Aging Hair Serum, 2.3 fl oz — Leave-in scalp treatment with peptides for fuller-looking, color-safe hair

NIOXIN Age Defense Anti-Aging Hair Serum is a lightweight, leave-in scalp treatment designed to help preserve hair color, improve density appearance, and refresh scalp vitality with peptides and botanical actives.

This serum targets common signs of aging hair—such as early greying, reduced fullness, and a dull finish—by delivering a blend of ingredients formulated to support scalp health and hair appearance. Designed to be used as part of the NIOXIN Age Defense regimen, it layers easily under styling products and is safe for color-treated hair. The formula is free from sulfates, parabens, and silicones and focuses on nourishing the root area where changes first appear.

How does this serum support a fuller-looking hairline?

The formula contains peptides and caffeine that work at the scalp level to help improve the look of density and body. Regular topical use can make strands appear thicker and reduce the visual effects of thinning by enhancing lift and moisture at the root.

• Black oat peptides to support hair fiber resilience
• Caffeine to stimulate scalp circulation for enhanced strand support
• Lightweight texture that won’t weigh hair down

Can this treatment help delay the appearance of gray hair?

Rather than reversing grey, the serum includes ingredients aimed at supporting the scalp environment and melanin-related pathways associated with natural color. It’s formulated to promote healthier-looking roots and may help extend the visual life of natural color when used consistently.

• Niacinamide to support scalp health and even-looking complexion at the root
• Black oat peptides intended to support pigment-related activity
• Daily leave-in application for ongoing color-preserving support

How do I use the NIOXIN Age Defense Serum in my routine?

Apply to a clean, towel-dried scalp focusing on areas where aging signs are most visible. Use the recommended dropper or nozzle to dispense a few drops and massage gently; leave the product in—no rinse needed. It layers under styling products and works with other NIOXIN Age Defense items for a complete approach.

• Use after cleansing and conditioning on damp hair
• Apply directly to the scalp and gently massage until absorbed
• Compatible with color-treated hair and daily styling

Is this safe for color-treated or chemically processed hair?

Yes. The formulation excludes sulfates, parabens, and silicones, making it suitable for treated hair types. It’s designed to be gentle while helping maintain vibrancy and manageability.

• Free of sulfates, parabens, and silicones
• Formulated for compatibility with color services
• Non-greasy finish suitable for daily use

Who is this for: The NIOXIN Age Defense Anti-Aging Hair Serum is intended for anyone noticing early signs of hair aging—reduced density, emerging grey, or lifeless texture—who wants a leave-in option to support scalp health and the appearance of fuller, more vibrant hair. It’s suitable for men and women, safe for color-treated hair, and best used as part of a regular scalp care routine to help maintain a youthful-looking finish without heavy residue.
