Okay dude! Do NOT pull on it whatever you do . Last thing you need is losing hair for no reason on a nice new piece. Best thing you can do right now is spray some lace release on the hair that is stuck together and leave it for a minute so it loosens out. Then if that has worked wash your hair to get the alcohol out. If you still have to unattach then you should unattach i'm not 100 percent what you've done but you need to use release alcohol if hair is stuck.
