Glamista Hair clip-ins are made of 100% Remy Human Hair which are relatively tangle free, but keep in mind that any hair extensions will shed and tangle just as your own natural hair. You can expect to notice some shedding throughout their lifespan as you brush or style your extensions. Although, we recommend brushing your extensions regularly to minimize shedding in other ways. Maintaining the health of your hair extensions with proper aftercare will also play a big role in shedding, tangling and the overall lifespan of your hair extensions.
