Kolorbar NYC Salon owner Irena Naco and her stylists nurture healthy locks for a diverse clientele. While they daub hair with balayage and ombre highlights or smooth it with brazilian keratin treatments, sunshine pours in through a floor-to-ceiling picture window and a crystal chandelier shimmers above the reception desk. Private rooms overflow with peaceful music and aromatherapeutic scents while massage therapists knead tense sinews. In addition to drawing on their intuition, these experts take cues from their studies in anatomy, physiology, and therapeutic algebra.
