George Kelloyan knows how to treat celebrity manes—both Christina Applegate and Fergie trusted their tresses to his adept hands, which have been trained in London, Paris, Milan, and New York. Today, George draws on 20 years of experience as he leads and educates his stylists at El Coco International Salon & Day Spa. These artisans perform their services with plant-sourced Aveda products, such as conditioners with natural, mood-altering aromas and texture lotions infused with organic marshmallow root that go great with s'mores. Stylists tint coiffures with bold primary colors and natural hues, which brim with conditioning plant oils that prevent damage and lock in shine. Staffers also up the ante of relaxation with mani-pedis, waxing, and Aveda-inspired massages. For their hard work, these artisans have received best-of awards from Vogue and Improper Bostonian.
