Injection PU clip-in hair extensions represent the perfect fusion of convenience and invisibility. Combining the easy application of clip-ins with our advanced injection technology, these extensions feature clips attached to a PU strip on one side, while the hair is injected into a color-matched thin polyurethane strip on the other side. This innovative design creates the most invisible clip-in extension available, with no visible wefts or bulky attachments.
Unlike traditional clip-ins with fabric wefts or standard PU seamless clip-ins, the injection method ensures hair is evenly distributed into an ultra-thin, flexible PU strip that matches your hair color. The result is a completely undetectable, lightweight extension that blends seamlessly with your natural hair.
