How it works, and common myths

Charged micro-fibers electrostatically adhere to individual hair strands, instantly augmenting their perceived thickness and volume.

A little more technical

Hair fibers, typically made from keratin or plant-based materials, use an electrostatic charge to bond to existing hair strands, creating a denser and fuller appearance by camouflaging thinning areas.

Hair fibers, typically composed of keratin or plant-based materials, are electrostatically charged to adhere to existing hair shafts, thereby increasing the perceived density and volume of hair and providing direct scalp coverage to camouflage areas of thinning.

Material: Keratin Protein Fibers; Made from premium keratin—the exact same structural protein as your natural hair—for a seamless, undetectable blend.
Mechanism category: Electrostatic Adhesion; The fibers hold a natural static charge that binds them tightly to your existing hair strands, resisting wind and sweat without feeling sticky.
