There are many products that may be used to seal the wefts of your hair extensions. Suitable sealants include products designed especially for sealing weaves, fabric sealant, super glue, and even clear nail polish. Research available sealants to find the best product to suit your needs.
Select one bundle of hair extensions, and spread them across a flat surface, such as a table or counter. Be sure to cover surface beforehand to prevent damage. Apply sealant to entire weft of one side of the hair extension. Allow the sealant to dry before repeating on the other side of hair extensions. Repeat this process for all bundles of weave used in hair weave installation.
When installing hair extensions, use weft sealant on the ends of any pieces of extensions that are cut through the weft. If installing a weave without cutting wefts, you do not need to seal the wefts any further.
