The term "boyzilian" might make a few people giggle, but at Nickel Spa in the Castro, man-waxing is a serious beauty matter. Nickel is one of the few places that offer waxing services for every possible inch of the male body. "If there's hair there, we'll wax it" should be the unofficial motto of the men-only spa's waxing experts. While the back is the most requested body part for waxing, the boyzilian, extended bikini, and "manscaping" (body trimming with clippers) round out the spa's extensive menu. Aestheticians here know how to put men at ease — they even use two kinds of wax (hard and soft) for different areas of the body. The spa also offers facials, massages, wraps, and scrubs (the chocolate scrub smells heavenly) designed especially for men. For the uninitiated, stay out of the sun and keep your skin cool and dry before your waxing treatment. Waxing for the back starts at $45, the boyzilian $85, and brows $20.
