Extensions applied with ultrasound are very delicate with respect to other systems such as adhesives or wax. The acoustic waves create pressure on the keratin modifying its structure therefore bonding strands and hair together. This method is adapt for hair and scalp and allows creating hardly perceptible bonds. The bonding is flat and therefore the extensions and the client’s hair mix together perfectly and naturally.
When Great Lengths introduced the ultrasonic technology onto the market in the year 2000, this came up to a revolution in the modern hair extension and densification. The points of attachment were no longer round such as with the heat technology, but for the first time they were flat and adjoining. This new bonding quality improved the wearing comfort, made the attachment points even less visible and at the same time better protects the natural hair. Even after many applications hair remains completely intact and healthy.
