Davines Heart of Glass Intense Treatment Blonde Strengthening & Brightening Hair Mask — 5.07 fl oz, Biacidic Bond Complex

Davines Heart of Glass Intense Treatment is a reinforcing and brightening hair mask formulated for natural and color-treated blondes to strengthen the fiber, reduce breakage, and boost radiance.

This intensive cosmetic mask combines the Biacidic Bond Complex with Baobab extract to target weakened blonde hair. It delivers deep nourishment without weighing hair down and helps restore surface brightness for a clearer, more luminous blonde. The fragrance opens with fresh citrus and spices, moves into green and soft floral notes, then settles into warm woods and musk for a refined sensory finish.

How does this mask strengthen fragile blonde hair?

The formula works on the hair structure using Davines' Biacidic Bond Complex to reinforce connections inside the fiber, making strands more resilient. Baobab extract adds moisture and elasticity to reduce the likelihood of breakage during styling and combing.

• Biacidic Bond Complex supports internal fiber reconstruction
• Baobab extract improves elasticity and moisture retention
• Rich conditioning agents smooth the surface to limit mechanical damage

Will this product help brighten dull or yellowed blonde tones?

This treatment is designed to visibly enhance brightness without using harsh pigments. By smoothing and nourishing the hair surface, it reflects light more evenly for a cleaner, fresher-looking blonde.

• Improves light reflection for an immediate brightening effect
• Safe for both natural and artificially lightened hair
• Non-pigmented formula focuses on health and shine rather than toning

How should I use the mask for best results?

Apply to towel-dried hair after shampooing, focusing on mid-lengths and ends where damage and discoloration are most visible. Leave on according to your hair needs—shorter for light conditioning, longer for deeper reinforcement—then rinse thoroughly.

• Use 1–2 times weekly for maintenance, more often for very weakened hair
• Distribute evenly with fingers or a wide-tooth comb for full coverage
• Rinse with cool or lukewarm water to seal the cuticle and boost shine

Does the fragrance affect sensitive scalps or color longevity?

The scent profile is a layered blend of citrus, green notes, florals, and warm woods. It’s formulated for a subtle, lasting finish; however, if you have a sensitive scalp, perform a patch test or consult a stylist before regular use to ensure compatibility.

• Fresh citrus and spice top notes for an uplifting opening
• Crisp green and soft florals at the heart for balanced sweetness
• Warm woods and musk in the base for a smooth, lingering finish

Who is this for: Davines Heart of Glass Intense Treatment is aimed at anyone with natural or color-treated blonde hair seeking to strengthen compromised fibers, reduce breakage, and improve overall brightness without using pigment-based toners. Ideal for people who want a nourishing, sensory-rich mask that supports hair integrity and enhances shine while maintaining a lightweight feel.
