AstroLift™ reparative volume spray

The AstroLift™ Reparative Volume Spray by K18 is a lightweight, reparative volume spray designed to reverse the bounce-depleting damage that robs hair of its natural body. Delivering flexible, touchable, humidity-resistant volume that lasts up to 2 days, with or without heat.

Reparative volume spray with hair fibre volumizing blend

AstroLift™ fundamentally reimagines what a volumising spray can do.

Where traditional products simply deposit surface-level polymers for a temporary illusion of lift, AstroLift™ works at two levels simultaneously, from the inside out, for results that genuinely build over time.

Internally, the patented K18PEPTIDE™ targets and reverses the molecular damage that erodes hair's resilience and natural elasticity, the underlying cause of volume loss that's too often overlooked, particularly in fine, fragile, aging or breakage-prone hair.

At the surface, the hair fibre volumising blend increases hair diameter by up to 25% and creates separation between strands for visibly fuller, airier hair throughout.

The lightweight, non-sticky, humidity-resistant formula of K18 volumizing hair spray applies to towel-dried or dry hair with or without a blow dryer, and delivers volume and bounce that lasts for up to 2 days without reapplication.

The benefits of K18 long-hold volumizing spray for fine hair

• Natural volume and hold for up to 2 days: soft, movable, touchable body that holds up against humidity and lasts well beyond the initial style, without daily reapplication.
• Repairs the root cause of volume loss: molecular damage that compromises the hair fibre's resilience and natural spring is addressed from within, restoring the hair's ability to hold its shape.
• Visible hair fibre thickening: hair diameter increases by up to 25%, strands appear denser and hair gains body and fullness from roots to ends.
• Humidity resistance: a sustainable, renewable natural polymer forms a weightless barrier against humidity for volume that never falls flat.
• Weightless and flexible: a non-sticky, non-crunchy formula that builds without heaviness and layers seamlessly with other styling products.
• Versatile, heat-optional formula: works with or without a blow dryer, helping minimise heat and mechanical damage during styling.

Clinically proven results from the K18 AstroLift™ Reparative Volume Spray*

• 2.5x more all-over volume.
• Touchable volume and bounce lasting up to 2 days.

Key ingredients

• K18PEPTIDE™ – a patented bioactive peptide that penetrates the hair fibre to reverse the molecular damage that depletes natural resilience and elasticity — the primary driver of lasting volume loss
• Hair fibre volumising blend – a complex of film-forming polymers that increases hair diameter by up to 25%, creates separation between strands and delivers generous, natural-feeling volume without heaviness or buildup
• Humidity-resistant natural polymer – a sustainable, renewable polymer that forms a lightweight barrier against moisture, preserving volume in all conditions
• Palmaria palmata extract – a red algae marine active that strengthens the hair fibre, improves suppleness and supports overall hair health
• Tocopheryl acetate – a stable form of vitamin E that protects the hair fibre from oxidative stress and environmental aggressors

A reparative volume spray for all hair types, particularly recommended for fine, fragile, aging and breakage-prone hair.

How to use the K18 AstroLift™ Reparative Volume Spray

Shake well. Hold the bottle 4–6 inches from roots and hair. Spray generously throughout on towel-dried or dry hair. Blow dry for amplified volume, or air dry for a more natural finish.

Apply after all other K18 products (mask, oil) to finish the style.
For best reparative results, wait 4 minutes after application before styling.
Can be reapplied between washes to revive bounce and body.
