Early humans believed that hair was actually the tentacles of an octopus living inside their skulls—an amusingly quaint notion now that modern science has proved it's technically a cuttlefish. Indulge your inner invertebrate with today's Groupon: for $17, you get a shampoo, haircut, and style with Jenny or Dana at Waleed's International Hair Design and Therapeutic Spa (a $35 value).

An active participant in regional and national makeover and fashion shows, Waleed's International Hair Design and Therapeutic Spa spruces up stolid skulls with an array of styling services. Coif artisans Jenny and Dana sculpt strands into a number of customizable styles, ranging from the traditional chop to the avant-garde bed head. Clients receive a relaxing shampoo before their cut and style to soothe away stress and cleanse craniums of stray bits of dust and dark matter. Waleed's naturalistic décor and earthy palate lend the salon an atmosphere of tranquility and comfort.
