Its the GTBG spike glue.I first put on the Labella spike glue,and while its still wet,I put on the
GTBG.The trick is to get hair unit on before the glues dry.I l wait a few minutes and on it goes.
Let the hair unit dry with the glue,on your head.Trust me,when done correct the bond is very strong.
It might take a few times but you will get it.The freeze spray is a great first skin before using
NextGen glue.The stuff dries in a minutes.Its a poor mans scalp protector.
