NIOXIN Density Defend Anti-Breakage Strengthening Mask for Damaged Hair — Lightweight, DensiPROTECT Repair

NIOXIN Density Defend Anti-Breakage Strengthening Mask is an intensive salon-strength treatment that fortifies weakened, damaged hair to reduce breakage and restore smoothness.

If your hair feels fragile, brittle or shows visible split ends, this deep-conditioning mask is formulated to reinforce the hair shaft while delivering moisture without weighing strands down. Powered by NIOXIN's DensiPROTECT Technology and more than three decades of thinning-hair research, the mask targets areas of damage to improve manageability, support thicker-looking hair and leave a soft, non-greasy finish.

How does the mask make damaged hair stronger?

The formula works by penetrating the hair fiber to rebuild resilience along the shaft, helping fragile strands resist snapping during styling and brushing. Instead of just coating hair, it supports structural integrity so improvements persist between washes.

• DensiPROTECT Technology helps reinforce weakened hair fibers.
• Deep-conditioning actives hydrate and improve elasticity.
• Targets split ends and areas prone to breakage for visible smoothness.
• Lightweight delivery avoids buildup that can mask volume.

Will this mask weigh my hair down or leave it greasy?

No — the Density Defend mask is formulated to be lightweight and rinse clean, providing hydration without a heavy residue. It improves softness and manageability while preserving natural movement and volume, suitable for daily or periodic use depending on your routine.

• Non-greasy texture absorbs quickly into strands.
• Rinses out fully to maintain natural lift and body.
• Safe for use on color-treated hair without dulling shine.
• Balances moisture so fine hair stays bouncy, not limp.

How should I use the NIOXIN strengthening mask for best results?

Apply after shampooing to towel-dried hair, focusing on mid-lengths and ends where damage is most common. Leave on for the recommended time to allow active ingredients to work, then rinse thoroughly and style as usual; regular use yields the best visible improvement in strength and texture.

• Use post-shampoo on damp hair for even distribution.
• Concentrate on fragile zones like ends and chemically treated areas.
• Allow a few minutes for deep conditioning before rinsing.
• Integrate into weekly or biweekly care based on hair condition.

Can people with thinning hair or color-treated hair use this product?

• Designed to complement thinning-hair routines and scalp health.
• Compatible with color-treated and chemically processed hair.
