K18 AstroLift Reparative Volume Spray for Thin, Fine Hair — 1.6 fl oz, Lightweight 2-Day Hold & Humidity-Resistant

K18 AstroLift™ Reparative Volume Spray is a lightweight, buildable volumizing mist that uses K18PEPTIDE™ plus hair-fiber technology to visibly lift and thicken thin, fine, or fragile hair for up to two days of touchable volume and bounce.

Combining the brand’s signature peptide repair technology with a targeted volumizing blend, this non-sticky, humidity-resistant spray addresses both the causes and appearance of limp hair. It’s formulated to restore elasticity lost to damage while adding targeted lift from roots to ends. The result is fuller-looking, resilient hair that keeps shape without crunchiness or residue.

How does AstroLift repair damage while adding volume?

AstroLift relies on K18PEPTIDE™ to fortify weakened hair structure, reducing the bounce loss that often accompanies damage. Simultaneously, a hair fiber volumizing blend adheres to strands to increase perceived thickness without weighing hair down.

• K18PEPTIDE™ targets and repairs internal hair bonds for resiliency.
• Fine fibers coat strands to create thicker-looking hair from roots to tips.
• Lightweight carrier ensures lift instead of flattening.

What kind of hold and finish can I expect for daily styling?

The formula delivers flexible, touchable hold that lasts up to two days, letting hair move naturally while retaining volume. It’s formulated to resist humidity and won’t leave a sticky or crunchy feel, so styles look polished and soft to the touch.

• Buildable hold for everything from subtle lift to stronger volume.
• Non-sticky, non-crunchy finish perfect for restyling between washes.
• Humidity-resistant ingredients help maintain shape in damp conditions.

How do I use the spray for best long-lasting results?

Apply to dry or slightly damp hair before styling or after using K18 treatments to amplify repair benefits and volume. Spray at the roots and work through mid-lengths with your fingers or a brush, then style with blow-dryer or let air-dry for natural lift.

• Hold bottle 6–8 inches away; mist roots and areas needing lift.
• Use sparingly to build volume—several light layers beat one heavy layer.
• Pair with heat styling to lock in extra lift, if desired.

Will AstroLift weigh my hair down or leave residue?

No—its lightweight formulation was developed specifically for thin and fragile hair types, so it adds body without heaviness. It leaves hair soft, touchable, and free of visible residue, allowing natural movement and easy restyling.

• Low-weight polymers prevent flattening while creating structure.
• Non-greasy formula avoids buildup that can make hair look limp.
• Designed to feel natural, not stiff or tacky.

Who this is for: K18 AstroLift Reparative Volume Spray is designed for people with thin, fine, or fragile hair who want instantly fuller-looking hair plus ongoing repair benefits. It’s ideal for anyone seeking a lightweight, buildable boost that resists humidity, stays touchable, and complements K18’s repair products.
