Sona Bella Salon and Day Spa

The stylists at Sona Bella Salon and Day Spa pamper bodies from head to toe, starting at the top with precision haircuts down to pedicures that incorporate whirlpool footbaths and sugar scrubs. Before acquiring a fresh hair coloring, clients can pamper the face their locks will frame by getting a chemical exfoliation, microdermabrasion, or a cleansing facial. The spa’s aestheticians also tend to epidermises with waxing, aiding recovering Elvis impersonators by banishing their sideburns or readying clients for the beach by revealing satin-smooth legs. The spa’s nail technicians turn their attention to appendages with Creative Nail Design shellac polish, and massage therapists deepen relaxation with hot stones and Swedish maneuvers.
