Evil,
horrible things. Somewhat like the normal
hair on your
head, but lacking the
color of it, and with a slightly different
texture. Can be from
silver to
white.
A really scary sign that you are starting to get older than you'd like. Though it's possible some may like that color hair, most people don't. People often start coloring their hair to prevent those things from being seen once they're past the stage at which you can pluck them out.
