AstroLift™ reparative volume spray
Interdimensional biotech reverses damage for clinically proven 2-day hold
A lightweight, buildable volume spray, powered by K18PEPTIDE™ to reverse bounce-depleting damage that can impact all hair types—especially fine, fragile, aging + breakage-prone hair. Hair fiber thickening, non-sticky blend helps hair look and feel fuller, delivering flexible volume for up to 2 days*—with or without heat styling on dry or towel-dried hair.
will it cause crunchiness or stickiness?
No, this lightweight, non-sticky formula provides flexible lift + hold without leaving hair sticky, crunchy, or weighed down. For best results, apply 4-6 inches away from hair and scalp.

can I reapply it every day?
You can reapply this buildable volume booster every day, but the 2-day style memory means you can skip re-application, and still get interdimensional lift.

when do I use it in my routine?
AstroLift™ can be applied AFTER all K18 products, including the mask + oil, to finish your style on towel-dried or dry hair. You can also apply products on top of our buildable AstroLift™ formula without weighing hair down.

Is AstroLift™ activated by heat?

Received this as a sample with my previous order, then purchased the full size because it worked so well. Many products leave my hair feeling greasy, but this added volume with zero greasiness

I used this spray after purchasing and receiving. I didn't have any hopes one way or the other on the sprays performance. However, I was so pleasantly surprised in that it held. Hair in place but in a natural flowing manner. It was amazing to see that my hair had a lot bounce more than ever before.
I'm pleasantly surprised and will continue purchasing. I just bought a regular large size and refill my little small handbag sprayer. It works out perfectly well. Thanks K 18.
