I live in Texas, so 100+ degree days are common. I was using a 100% lace system, but found that in the heat, my bond would begin to seep thru the lace, and I had bond in my hair. This made it hard to maintain, and look the same day after day. So we moved to a hybrid. I now have a lace front, and around the temple area, it is poly (I use dermal Lines). In the veri center it goes back to lace. I feel it is more breathable than poor, and heat can. Escape. On the perimeter area where I’m. Using poly, I use a bond in addition to tap. Onthe front of the system, I’m using Devlin adhesive bond, and on the very top of my head where it is also lace, I’m not using anything.
Not using any bond or adhesive on the top is a true compromise. The bond in my hair issue is resolved, it is cooler than poly- so all good. But it took some getting use to. I feel a difference when I do simple things like make facial expressions, or when I sleep, I can feel the lace move on my head. I was worried I’d accidentally rip it off when I slept, but I haven’t. The bond and. Tape has kept it well afixed to my head. I can easily clean my visible hairline on the front. So overall it works well.
Now that it is cooling off, I’ll keep the poly perimeter, but just go with bond on my entire system and ditch the tape. With poly and tape, I can easily feel the transition from my bio hair to the system. No one can notice it of course, but I’m a bit self conscious about it.
