Mate,

Attach it well and you will forget it's there - it just becomes a piece of you. Wind, rain, swimming, driving in a convertable, surfing, working out at the gym, washing the hair every day...all part of my daily life and to me, they make no difference.

The only time you will be worrying about your hair piece is if it's not attached well, or if the color is way off. You can easily fix the color by way of styling (gels, waxes, etc), but there's no excuse for going out with a poorly attached picece. Period.
