4 oz, What it is: When it’s time to remove those beautiful Fusion extensions, we have the solution you need. It’s our Keratin Bond Remover, which breaks down the keratin bonds so you can slide the hair extensions out of the natural hair. What it does: Dab a small bit on the keratin bond. Let it set for a few seconds, then use the Hair Extension Tool to squeeze the bond until it breaks and loosens. After the extensions are removed, wash hair. What else you need to know: Don’t use the Keratin Bond Remover to remove Tape-In Extensions.
