How do you guarantee flawless hair and makeup on your wedding day without taping a bridal-magazine picture to your face? You hire Grace Hair & Body's Grace, a Vidal Sassoon?trained hairstylist, and April Dawson, a makeup artist for ABC network television. The duo travels to event sites to whisk hair into elegant updos and enhance facial features with high-quality cosmetics. Grace Hair & Body doesn't stop with wedding-day services, either. Its professional technician, Angela, offers noninvasive i-lipo treatments, and Nicholas, the massage therapist on staff, delivers deep-tissue, Swedish, and shiatsu massages.
