Hopefully you did not use a whole block of TemBond® for 1 application. There is typically enough material for 2-3 full head hair extension applications in each package of TemBond! The bundle of extension which you are dipping should be small (1/4 inch flat on a ruler and ⅛ inch bundled) to seal at the root hairs and eliminate shedding of extension hairs. Too large bundles attached to too few hairs may cause the hairs to be pulled out or shed the extension hair.
Refills can be purchased in our store.
