When you walk into thirteen, you'll be whisked away to a hair fantasyland. A highly trained hair stylist will help you figure out the best cut ($35 and up) for your face and personal style. If you already know what you're looking for, the stunning staff of stylists can take your vision and transform it beyond expectations. A single-process color is $36 and up, while partial highlights for dull head threads start at $60. Narrow down the focus to ocular hair with eyelash extensions ($125–$350), or wax away unwanted peach fuzz beneath an arched brow ($20–$25), on the stiff upper lip and trembling chin ($29), or from the bikini line ($30). Save today's Groupon for the largest day and use it for bridal makeup, which costs $225 for the bride and $85 for each doting handmaiden. This Groupon is also valid toward specials, such as half-price Friday facials, which occur once a month, enabling visitors to fully indulge in a European facial (regularly priced $95) or firming facial (regularly priced $165) for half-off.
