A rainbow wall of haircare products from Aveda, Moroccan Oil, Matrix, and Bed Head fills the sunny storefront of Rosci Salon Da' Spa. Inside, stylists rely on these crèmes to fashion three types of wave perms or conceal salt-and-pepper coifs with liquid chroma. Continuing education classes have trained their nimble fingers, which channel both men and women's styles and weave in silky human hair extensions with durable nylon bonds. In private treatment chambers, beds support bodies during eight therapeutic and relaxation massages, and Bioelements blending labs put fragrance- and color-free tonics at aestheticians' fingertips to mix into facials for every skin type. OPI polish slicks natural nails and acrylics in high-gloss color, and Jane Iredale makeup protects skin from air pollutants and UV-rays while fooling facial detection software in red-light runner cameras.:m]]
