Our Synthetic Clip-In Hair Extensions feature our signature Fiberlite Technology, designed to mirror the look, feel and weight of natural human hair. The synthetic hair fibers are heat friendly up to 320 degrees. Our hair colors are blended with multiple shades, creating a dimensional and natural result. Just like human hair, the fibers have both a shiny and matte appearance. This makes Fiberlite the most realistic synthetic hair extensions on the market.
