Drybar Liquid Glass Miracle Smoothing Sealant — 6.4 oz for Fine-Medium Hair, Lightweight Heat-Activated Frizz Control & Shine

Drybar Liquid Glass Miracle Smoothing Sealant is a lightweight, heat-activated finishing treatment that seals individual strands for long-lasting frizz control and high-gloss shine.

Designed for fine to medium hair, this 6.4 oz sealant uses heat-activated technology and vegan keratin to form an invisible protective layer around each strand, smoothing the cuticle and resisting humidity through multiple washes. It also provides thermal defense up to 450°F (232°C) and leaves a soft, silky finish without weighing hair down. The Blanc fragrance blends coconut, amber and vanilla for a subtle, salon-style scent.

How does this sealant work to reduce frizz?

The formula uses heat to activate a smooth-coating complex that wraps each hair shaft, helping to lock down the cuticle and block moisture that causes frizz. Vegan keratin and burdock root work together to reinforce and hydrate the hair surface for a sleeker look. Results persist through several washes, so styling holds longer between shampoos.

• Heat-activated Smooth Shot Complex forms an invisible shield around strands
• Vegan keratin moisturizes and smooths the cuticle
• Burdock root helps control surface-level frizz and flyaways
• Lasts up to three washes for extended manageability

Will this weigh down fine hair or change styling feel?

No — the sealant is formulated to be lightweight so it smooths and adds shine without heaviness. It leaves hair feeling silky rather than coated, which helps fine and medium hair retain volume and movement. Apply sparingly, focusing on mid-lengths and ends for best results.

• Lightweight texture designed for fine to medium hair types
• Non-greasy finish maintains natural movement and body
• Use a small amount to avoid buildup on roots

How should I use it with heat styling tools?

Apply the sealant to damp or dry hair before using a blow dryer or flat iron so the heat-activated ingredients can form their protective layer. It offers heat protection up to 450°F (232°C), making it suitable for most styling tools when used as directed. Finish with a quick pass of your iron or a blast from the dryer to lock in the glossy result.

• Work a pea-to-quarter-sized amount through mid-lengths and ends
• Blow-dry or flat-iron to activate the sealant’s shield
• Safe for styling tools up to 450°F (232°C) when used correctly

What sensory and ingredient highlights should I expect?

The sealant delivers a super-glossy, silky finish and a subtle Blanc scent combining coconut, amber and vanilla notes. Key actives include vegan keratin for cuticle smoothing and burdock root for frizz prevention, while the Smooth Shot Complex provides the heat-activated sealing effect. The formulation aims to balance hydration and weightlessness for polished, touchable hair.

• Blanc fragrance with coconut, amber and vanilla accents
• Vegan keratin for moisture and cuticle reinforcement
• Frizz-fighting burdock root extract
