WigPal lace glue is a wonderful water based product, does very little to no damage to the lace, edges and most important the scalp! Our lace glue is more than capable to hold up to 2-3 weeks. WigPal lace glue is applied as white but dries  up to a wonderful invisible layer. Not only does it give out a amazing bond but it also is lab tested and safe to use on skin! Not recommended for those who have skin disorders or high sensitive skin. Be sure to have a professional to apply product for the safest and best outcome.
