Biolage Full Rescue Restorative Hair Mask for Thin Hair — 16.9 fl oz, Rosemary Oil & Niacinamide, Silicone-Free

This restorative hair mask was created to treat fine or thinning hair that needs strength and moisture without excess weight. The formula pairs a steam-distilled rosemary oil concentrate with triple-purified niacinamide to support scalp balance and help hair retain hydration, while a gentle, silicone-free base smooths and seals strands from root to tip. Use it as a weekly deep-conditioning step to restore suppleness and add the appearance of density across the hair shaft.

How does this mask improve the feel of thin hair?

The mask delivers targeted moisture and smoothing ingredients that refresh texture without heavy residue. Lightweight conditioning agents work quickly to soften, while niacinamide helps the scalp maintain hydration levels so strands feel more resilient.

• Light, silicone-free formula prevents weighing hair down
• Rosemary oil concentrate helps invigorate the scalp and strands
• Niacinamide supports moisture retention for a fuller touch
• Seals cuticle layers for smoother, silkier hair surface

When should I use the Full Rescue mask and how long should it stay in?

For best results, replace your regular conditioner with this mask twice a week after shampooing. Apply to clean, wet hair, massage evenly, and let it work for a short, effective period before rinsing.

• Apply after Full Rescue Shampoo to damp hair
• Massage through roots to ends for even distribution
• Leave on for 3–5 minutes for optimal absorption
• Rinse thoroughly and style as usual

Will this mask weigh down delicate or thinning hair?

No — the mask is formulated to add visible body and smoothness without heaviness. The silicone-free, lightweight blend moisturizes and conditions while preserving natural lift and movement.

• Non-greasy texture maintains natural volume
• Designed specifically for thin hair profiles
• Hydrates without coating strands in heavy silicones
• Leaves hair easier to style and fuller-looking
