It's a hairpiece-like we all wear. I'm guessing the integration comes from having a wider spacing between the squares of lace that the hair gets pulled through. Imagine the time taken to get that fitted/removed/cleaned etc? It's a pain taking a normal piece off, let alone having something like that removed often enough not to cause hygiene problems. Then imagine trying to disguise a wide spaced piece of lace on your scalp that's actually mingled with your real hair...just think it through for a few minutes. You need to search more on the net & see if this a viable option-sounds like a nightmare to me. Regards
