I would also like to know as well since I have a skin piece.
But as far as removing, you'll have to spray on the solvent I believe. I am getting ready for my first detach and re-tach...I'm very nervous and want to make sure it looks just as good as day 1 and that I put it in place correctly.
i been wearing lace and was thinking nabout crossing over to a skin piece, more or less because i read they last longer with the shedding, how is your hairline, do you have any pics
