Sometimes redoing the front is a pain the ass, cause its still on your head and u might have residue stuck to the lace etc, and kind of hard to do a mirror slide when its on your head. I guess you can try using bubble wrap or seran wrap etc.. I can see the appeal tho of what makell does.. uses the freeze spray on the front and tape on the base. that way its easy to keep redoing your hairline every couple of days.
