Davines Heart of Glass Sheer Glaze Blonde Leave-In Thermal Fluid, 5.07 fl oz — Brightens, UV & Heat Protectant

Davines Heart of Glass Sheer Glaze is a leave-in thermal fluid that brightens and protects natural or color-treated blonde hair while adding shine and heat resistance up to 230°C/450°F.

This lightweight, leave-on formula is formulated specifically for blondes to hydrate strands, enhance shine and defend against heat and UV exposure. Infused with the brand’s Fortifying Botanical Shield, the fluid helps restore elasticity and resilience to fragile hair fibers, making blowouts last longer and hair look polished without weighing it down. The fragrance opens with citrus and spice, moves to green and soft floral notes, and settles on warm woods and musk for a subtle, long-lasting scent.

How does this product protect hair from heat and sun damage?

Sheer Glaze creates a protective coating around each strand to minimize direct heat impact and reduce UV-related color fading. It’s designed to defend hair from styling temperatures up to 230°C / 450°F, helping preserve fiber integrity during blow-drying and thermal styling.

• Thermal protection up to 230°C / 450°F
• UV filters to limit sun-related discoloration
• Lightweight film that reduces moisture loss during styling

Will this make my blonde hair brighter without changing the tone?

The formula brightens and enhances the natural or dyed blonde without depositing pigment, so it refreshes luminosity rather than altering shade. Regular use adds reflective shine and helps diminish the dulling effect of environmental stressors.

• Optical brightening for increased radiance
• No color-depositing agents — safe for natural and color-treated blondes
• Adds glossy, reflective finish for visibly brighter hair

How should I use Heart of Glass Sheer Glaze for best results?

Apply a small amount to towel-dried hair from mid-lengths to ends, then comb through and style as usual with a blow dryer or thermal tool. It’s a leave-in product, so do not rinse out; you can reapply a small quantity on dry hair for added shine or smoothing.

• Use on damp hair before blow-drying or heat styling
• Distribute evenly with fingers or a comb for full coverage
• Can be layered lightly on dry hair for extra gloss and frizz control

What benefits does the Fortifying Botanical Shield provide?

The patented Fortifying Botanical Shield works to strengthen and add elasticity to the hair fiber, helping reduce breakage during styling while extending the duration of a blowout. It supports hair structure so strands feel more resilient and look healthier over time.

• Improves fiber elasticity and resistance to mechanical stress
• Helps maintain style longevity and reduces breakage
• Light conditioning without weighing hair down

Who this is for: Davines Heart of Glass Sheer Glaze is made for people with natural or color-treated blonde hair who want a lightweight leave-in that boosts shine, defends against heat and UV exposure, and helps maintain blowout results. It’s ideal for those seeking a protective styling step that enhances brightness and improves strand resilience while leaving a fresh, subtle citrus-wood fragrance. Recommended size: 5.07 fl oz—sufficient for regular at-home styling or professional use.
