K18 AstroLift Reparative Volume Spray — 118 ml | Damage-Repair Volumizer with Flexible 2-Day Hold

K18 AstroLift Reparative Volume Spray is a lightweight, buildable volumizer that repairs bounce-reducing damage with K18PEPTIDE™ while adding fuller-looking lift and flexible, humidity-resistant hold for up to two days.

Every spritz pairs the patented K18PEPTIDE™ with a hair-fiber volumizing complex to address the structural damage that makes hair limp, then deposits fine-thickness fibers that create root lift and strand body without weight. The formula is designed for fine or damaged hair types that need noticeable volume without stiffness, tackiness, or a crunchy finish.

How does AstroLift actually restore volume to damaged, fine hair?

The spray works in two complementary ways: K18PEPTIDE™ targets damage within the hair’s inner structure that reduces spring and bounce, while the volumizing fiber blend wraps strands to increase apparent diameter and root lift. Together they make hair look and feel fuller from roots to ends without coating or weighing hair down.

• K18PEPTIDE™ helps reverse damage that causes loss of bounce and resilience.
• Hair fiber volumizers add micro-thickness to strands for visible lift.
• Light, buildable formula allows layering without stiffness or residue.

Will the spray hold style through humidity and for how long?

AstroLift gives a flexible, touchable hold that resists humidity and maintains lift for up to two days with standard daily activity. It’s formulated to be non-sticky so hair remains moveable, not locked into place, making it suitable for styles that need natural motion.

• Flexible 2-day hold keeps body without crunch.
• Humidity-resistant finish helps preserve volume in damp conditions.
• Non-sticky texture allows restyling and touch-ups.

How do I use this spray for best, long-lasting volume?

For root lift, shake well and spray 6–10 inches from roots on towel-dried or dry hair, then style with a blow dryer or diffuser to set. Layering a few light sprays along mid-lengths and ends builds all-over thickness while preserving softness and movement.

• Apply on damp for stronger lift, or on dry for refresh and texture.
• Use heat when styling to enhance hold and shape.
• Layer gradually—formula is buildable without becoming sticky.

Is AstroLift safe for color-treated or chemically processed hair?

The formula is designed to be compatible with color-treated and chemically processed hair; it focuses on repairing and volumizing rather than stripping or harshly coating strands. As with any new product, test a small section first if you have concerns about specific treatments.

• Works on chemically treated hair to improve feel and lift.
• Lightweight ingredients avoid heavy buildup on color-treated strands.
• Compliments K18’s peptide-based repair approach for damaged hair.

Who is this for: K18 AstroLift Reparative Volume Spray is ideal for people with fine, limp, or damage-weakened hair who want visible lift and thicker-looking strands without stiffness. It suits anyone seeking a lightweight, buildable volumizer that combines reparative technology with styling performance—especially those who want touchable, humidity-resistant body for up to two days.
