If they are regular keratin, you should be able to use acetone or maybe an orange oil type remover and a pair of pliers. Saturate the bond with your selected liquid, crunch the bond with pliers, turn 1/4 or 1/2 turn and crunch again. You should be able to gently pull at the bottom of the strand and slide the extension out. If it doesn;t slide out easily, repeat saturation & crunch again.
If the bonds are like so cap or great lengths, I think you'll need grain alcohol to remove??
Good luck, and go slow. You can do alot of damage from improper removal. Also, be careful not to get the acetone in your eyes, seems like a no brainer, but I;'ve done it one more then one occasion....
