Hair that has been manufactured and stitched onto a weft can cause minimal shedding. To prevent shedding we recommend you use Weft Sealer along the track of each bundle. Do not stitch and knot around the weft and through the weft of the tracks. Just like your natural hair, all hair extensions will experience minimal shedding. Use a silk bonnet or wrap your hair while sleeping and keep the hair clean and conditioned to ensure your investment last for years. DO NOT CUT THE WEFTS.
