it could be but it's the other way around than a regular half wig. a regular half wig leaves the hair out in front. a lace front half wig is when you leave ur hair out in the back bc the front is glued to ur forehead. ur hair has to be as long as the lace front for it to look presentable. U can't have a 18" when ur hair is only 10". I hope I explained that well.
yes that is an option too. i forgot a/b that one. i saw a video of that on youtube. they already cornrowed all of her hair, applied the frontal, clipped the frontal out of the way, and proceeded to weave up the back that was left out.
