Our Take
A lightweight, buildable volume spray that combines K18PEPTIDE™ repair with a hair-fibre thickening blend that increases hair diameter by up to 25%. Delivers flexible volume for up to two days with or without heat, making it suitable for air-drying as well as blow-drying. Apply to towel-dried or dry hair after all other K18 products, then style as normal — wait four minutes for the peptide repair component to work. Launched in early 2025. Contains drying alcohol (Alcohol Denat.), which places it in cgm_modified territory. Most relevant for curlies and wavies with fine, low-density, or breakage-prone hair who want both repair and volume in one step.
