When your sweating, attaching hairsystems can be a nightmare, at least for me. One time i was really hot, in a place with no air conditioning, and my attachment failed so i had to take it off and try again, Now my nerves are kicking in, and once u start getting nervous or pissed off, you start sweating more. I was really disgusted and had to throw a hat on because i couldnt get it to attach, And i was using the blue tape too. all i know is for me, if im sweating and cant stop. i cant attach my system, even when i dried my head off with alcohol or a blow dryer, soon as u attach, I think u need a good 15 mins of dry scalp for the glue/tape to adhere, If you put it on and start sweating immediately the attachment goes capoot
