Drybar Liquid Glass Smoothing Sealant for Fine-Medium Hair — Heat Protects to 450°F, Lasts Through 3 Washes

Liquid Glass Moisture-Rich Miracle Smoothing Sealant is a heat-activated, lightweight finishing serum that shields hair up to 450°F for long-lasting frizz resistance and high-shine without weighing fine to medium hair down.

Designed by Drybar for salon-style blowouts at home, this sealant uses heat-activated polymers and Vegan Keratin to smooth and reinforce each strand. Its formula creates an invisible barrier that helps hair stay glossy and frizz-resistant for up to three washes while delivering a soft, silky feel. A subtle Blanc fragrance—coconut, amber, and vanilla—finishes the experience.

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

Liquid Glass contains heat-activated technology that forms a protective shield when exposed to hot tools, helping reduce direct thermal stress on the cuticle. Vegan Keratin provides moisture and strengthens the hair fiber so styling causes less surface roughness.

• Heat protection rated up to 450°F (232°C)
• Heat-activated polymers create a temporary barrier during styling
• Vegan Keratin helps reinforce and smooth the cuticle
• Lightweight formula avoids weighing fine to medium hair down

Will Liquid Glass help control frizz between washes?

The sealant delivers multi-wash frizz control by wrapping each strand in a moisture-rich finish that repels humidity and reduces flyaways. Results are designed to last through approximately three shampoos, depending on hair type and styling routine.

• Formulated to resist frizz for up to three washes
• Burdock Root extract supports smoother surface texture
• Creates a glossy finish that minimizes visible frizz and frayed ends
• Works best when applied before heat styling

How should I apply it to avoid greasiness or limp hair?

Use a small, targeted amount on damp hair focusing on mid-lengths to ends; avoid the roots to prevent weight. Activate the sealant with your blow dryer or flat iron to form the protective film and smooth the cuticle for extra shine.

• Apply 1–2 pumps to damp, towel-dried hair for fine hair; increase slightly for thicker mid-lengths
• Distribute evenly with fingers or a wide-tooth comb
• Blow-dry or style with a hot tool to activate the formula
• Reapply a tiny amount to dry hair sparingly for touch-ups

What sensory experience and ingredients should I expect?

The lightweight serum leaves a silky, glossy finish without stiffness. It features a Blanc scent—coconut, amber and vanilla—and uses Vegan Keratin plus Burdock Root to smooth and moisturize, avoiding animal-derived proteins.

• Fragrance notes: coconut, amber, vanilla (Blanc)
• Key actives: Vegan Keratin for support, Burdock Root to help prevent frizz
• Non-greasy, non-sticky finish suitable for fine to medium hair
• Designed specifically for blowout-style results

Who is this for: Drybar Liquid Glass Moisture-Rich Miracle Smoothing Sealant is suited for people with fine to medium hair who want salon-polished shine, heat protection, and multi-wash frizz control without adding heavy buildup.
