K18 AstroLift Reparative Volume Spray is a lightweight, buildable volume spray made for hair that has lost its bounce — especially fine, fragile, aging, or breakage-prone hair. It sprays on as a fine, non-sticky mist scented with warm, fruity floral notes, and dries down without the crunch, stiffness, or tackiness typical of traditional volumizing sprays. Hair comes away feeling fuller and looking lifted from the roots, with natural, touchable movement rather than a stiff, sprayed-in shape.Apply to towel-dried or fully dry hair, holding the bottle a few inches from the roots and spraying generously before blow drying for extra lift, or use on its own between washes to boost roots that have gone flat. AstroLift is powered by K18PEPTIDE™, the brand's patented biomimetic peptide, formulated to help address the bounce-depleting damage that flattens hair over time — for full strengthening benefit, K18 recommends waiting four minutes after application before styling. Alongside the peptide, a hair fiber volumizing blend increases hair diameter and creates space between strands for a fuller look and feel, while a humidity-resistant natural polymer forms a weightless barrier that keeps volume from collapsing in damp air. The formula isn't heat- or tension-activated, so it works whether hair is blow-dried, air-dried, or left alone.Key Benefits K18PEPTIDE™ is formulated to help address the bounce-depleting damage that affects fine, fragile, and aging hair over time. Hair fiber volumizing blend increases hair diameter and creates space between strands for a fuller look and feel. Humidity-resistant natural polymer , sustainably sourced, forms a weightless barrier against humidity so volume holds its shape. Buildable, non-sticky formula layers onto towel-dried or dry hair without stiffness or residue. Not heat- or tension-activated so it delivers lift with or without blow drying or hot tools. Style memory lasts up to two days so touchable volume and bounce carry over between washes. The result is root lift and all-over body that moves like natural hair, not a sprayed-in shape. Will it feel crunchy or sticky? No, this lightweight, non-sticky formula gives flexible lift and hold without leaving hair stiff or crunchy. Does AstroLift need heat to work? No, it's formulated to add volume with or without blow drying, which helps minimize additional heat and mechanical styling. When does it go in the routine? Apply AstroLift after other K18 treatments, such as the mask or oil, as one of the last steps before or after styling. {"@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [{"@type": "Question", "name": "Will it feel crunchy or sticky?", "acceptedAnswer": {"@type": "Answer", "text": "No, this lightweight, non-sticky formula gives flexible lift and hold without leaving hair stiff or crunchy."}}, {"@type": "Question", "name": "Does AstroLift need heat to work?", "acceptedAnswer": {"@type": "Answer", "text": "No, it's formulated to add volume with or without blow drying, which helps minimize additional heat and mechanical styling."}}, {"@type": "Question", "name": "When does it go in the routine?", "acceptedAnswer": {"@type": "Answer", "text": "Apply AstroLift after other K18 treatments, such as the mask or oil, as one of the last steps before or after styling."}}]}
