The seamless Cambodian Virgin clip-in hair extensions are also called invisible clip-on hair, or PU clip-in hair extensions. The hair extensions are made with a thin PU weft base, hair with clips pressed on it, which lays flat against your head and let you feel more seamless and comfortable. No salon is needed! Can be installed and removed at any time. Try out a new hairstyle for special events like a wedding, prom, or a hot date. Blend perfectly with your own hair. No one knows you have hair extensions.
