In addition to being a lifelong fashion accessory, hair is also an invaluable warning system, standing up when alarmed by encroaching birds of prey and static-charged balloons. Refurbish life's alarm system with today's Groupon: for $35, you get $90 worth of services at Gro Salon in Bucktown.

Catering equally to the tresses of men and women, Gro Salon's follicle- sculptors craft accentuating face frames in a variety of classic and trendy styles.
