Hi;
The I-lace is probably, in my opinion, the most realistic scalp appearance Ive ever seen, however, the material is a bit thicker than sfs or french lace and therefore may not be suitable for some hairlines. I word it like this because some have created a great look at the front hairline with i-lace, I just have never been able to. so, what most do is get an i-lace island which is i-lace in the middle with french or sfs lace around the perimeter. this is ok if you have a higher density to cover wear the two materials join together. you can attach i-lace just as you would any base, clean up is the same also.
release real well with 99% or lace release and then mirror slide if necessary. clean your scalp with PURE or any glue remover.
I hope this helps with some of your questions.
