December is the month to drink, dance, and be merry, so put that gym membership on hold until you restart those New Year's resolutions and let yourself indulge in some glamour. If your social calendar is half as packed as ours this holiday season (not bragging, but kind of), you're going to need manicures, blowouts, and maybe even some Botox to get you through (relax, it's mainstream now). Booking services à la carte can get pricey, but luckily some of our favorite beautifying spots in the city offer membership programs that save you money and earn you some perks while keeping you looking party-perfect. Consider it a Christmas gift to yourself.
