I always use got2b glued these days cause im lazy and its easy.. Hoever I don't like it for the hairline. It never attaches good for me. always lifts. So i use got2b glued for the base and cream glue for the front. I apply it on semi thick and just wait a little while till it feels tacky with my finger when touching it, than i smudge the system down and applie pressure and keep patting it etc.. I can get a good solid 3 days hold if im not sweating my brains out. One good trick.. Leave your own whispy thin hair .. It works better on toop of a little hair because the hairs almost anchor to the got2glued and extends ur hold time a lot.
