I know its not in Towson but I've gone to the Spa by Debbie for years. I went there when they started a spa in Perry Hall but they moved to the Avenue in White Marsh (next to the mall). They have also opened a second spa in Owings Mills. I get my hair done there, have had massages, and my bikini and brows done there. I always leave happy! I've also been to About Faces in Towson/Timonium, but only for a pedicure/manicure. They did a good job but it's "stuffier" there. Just be sure to get your brows done a few days before the 11th so the skin can calm back down. My skin is kinda reddish for a day or two after getting them waxed.
Have fun on your night out!
