Trend: Pixies & Bobs

"Spring and summer is all about a haircut," says Garren, a celeb hairstylist who's styled the likes of Gwyneth Paltrow, Agyness Deyn, and Madonna. "If you take the dare, you should cut your hair into a style because short hair is really popular. Especially the pixie cut or a really long front and a really short back -- you know, very asymmetrical. Like a bob haircut with a very short bang."

Katie Holmes, Agyness Deyn, Rihanna, and Paris Hilton have all taken the short hair dare -- would you?
