I have found that the longer you let the spiking glue dry the less of the stuff gets into your hair through the lace. But, yea you cant let it dry totally or it wont stick at all. My hairline always lifts after about 8 hours of wearing since attachment. Everywhere else is solid. My guess would be that its just oiler at the hairline breaking the bond down quicker. I am definitely going to try white glue at the hairline and got2b everywhere else tomorrow. Ill let you know how it works out for me.
