• SHIPS UPS GROUND ONLY!! Do not select Post Office, USPS, to ship • Alcohol Based • 4oz Bottle • Won't Damage Hair. Use Donna Bella's Bond remover to break down the bond quickly and gently without damaging hair. Because it's alcohol based, Keratin Bond Remover doesn't make hair slippery and makes clarifying unnecessary. Only a small amount is needed for each extension weft, so each bottle lasts a long time. Apply this hair extension removal solution to the keratin bond and make sure the entire bond is covered in the Bond Remover. Let it set for a few seconds, then use Removal Pliers to squeeze the bond until it cracks and breaks. Then the keratin bond and its weft should slip right off hair. After the extensions are removed, wash hair.
