Visible Density, Weightless Touch

Fine hair, but make it fuller. This thickening serum delivers instant density without heaviness, powered by arginine—an essential amino acid that helps reinforce the fiber and reduce breakage. Hair feels fuller, stronger, and naturally bouncy. Spray onto towel-dried hair, comb through, then air-dry or style as you like. With continued use, strands gain resilience and a healthy shine. The result: volume you can see and feel—light, lifted, and effortless.
