At Cadillac Nails by Mary, experienced nail technician Mary strengthens and resuscitates weary extremities with durable Shellac lacquer and botanical OPI polish. The 30-minute Shellac manicure begins by sculpting nails and corralling cuticles with a series of precision snips. Next, Mary applies a durable, glossy Shellac coating, which wears like a polish but strengthens nails for up to two weeks to help dominate in thumb wars and reduce instances of chipping during daily wear and tear. Clients choose from a vast assortment of colors or opt for a clear coat to capture a natural look. During the 45-minute pedicure, clients kick back and relax as Mary reanimates worn toes. The nail nurturer chases away calluses and artfully tends to cuticles before dressing them in botanical-based OPI polish to leave them aesthetically renewed and reflective enough to check post-salad smiles.
