Natural-looking hair extensions created with the Invisible Hair Extension System

Original methodologyIndividualized by design

The foundation of the system is an individualized approach. Instead of one placement pattern for every client, it takes into account natural density, texture, length, haircut, color, fragile areas, temple density, desired volume and length, bond size and weight, placement, distribution, movement and visibility.

Best for

Fine and thin hair, short hair, different densities, difficult transition areas, temple filling, extra volume and full transformations.

Goal

Extensions that blend naturally with your own hair — discreet attachment points, balanced density, natural movement and comfortable wear.
