The friendly, experienced stylists at What I Want? Salon refurbish damaged nails and dingy manes with an extensive roster of pampering services. A classic manicure begins with a scrupulous removal of polish past before nails enjoy a thorough filing and shaping into stately arcs de triomphe. Arms and hands eagerly plunge into soothing paraffin, where moisture seeps deep into pores and eliminates troublesome dryness. A final coat of polish from high-quality brands such as OPI cloaks colorless phalange shields in jackets of pigment. Alternately, lackluster locks get a glossy makeover with a glaze treatment, which seals the hair shaft with a healthy, mirror-like shine ideal for checking your reflection once mirrors power down for the evening. A shampoo and blowout rinse out excess product and lollygagging follicle debris. While waiting for the glisten to emerge, nosh on complimentary snacks, beverages, and robes and search What I Want?'s three-piece mural for symbolic imagery from ancient hair-based religions.
