i have a question about the polyskin wigs. you mentioned above taht you dont need to use tapes and glues, that you can use got2be glued. that sounds spectacular! how long will that last and would perspiration cause the piece to come off? im in the entertainment business and stage lights and stuff cause me to perspire alot, and i move around alot on stage. will this affect it? and would i be able to get an sfs front for the natural hairline?
