It's odd, I could never get G2B to work for me. It gave a weak 1 day hold at best, and I'm sure if someone pulled at my hair then it would have come off. So I very quickly gave up the idea of using this.
I have a UTS system.
I use a white glue - it's specific to my hair supplier but probably similar to other white glues. I apply just one layer on top of a scalp protector (this is a spray from Hair Direct). This gives me a solid 7 day hold and even up to 14 days with a hairline touch-up in between. And that's in hot weather.
I found the scalp protector to be a game changer for me. I only use it in hot weather (like on holidays, or summer in the UK) and it prevents sweat from weakening my bond. To think, my system held on very well during a 10 day holiday where the temperature outside was 40 degrees centigrade!
