"Three Ladies" joke

There are three ladies. Each walk into a salon at different times. A barber looks up as a
brown haired girl walks in. "
Wow. You have such
beautiful brown hair."
and the girl says, "
Thanks, it's natural."
she runs her hand through her hair. Then the blonde walks in. "
You have shiney blonde hair."
and the blonde does the same. "
Oh. Thanks. It's natural."
she ran her hand through her hair. Then an unusual green haired lady walks in. "
Your hair sure is different."
the barber says. "
Oh. Wow. It's natural."
she runs her hand up her nostrils, and to her hair!
