I would just like to advise anybody here (especially newbies) not to color a hairpiece. i think it's asking for trouble. you can't color it the way you normally would your own hair - you have to avoid the base so you inevitibly will have a blonde layer underneath. Plus, each hairpiece will take color differently, so you have to do lots of experimenting. it's just not worth it imo.

just color your own hair to match the piece, like ba says. that's much easier.
