Mega Colors can run anywhere from 5-8+ hours. We recommend a consultation before booking this service so we can determine how much time will be needed and if your hair is able to achieve the desired look. Please call the salon (480)539-7050 with any questions. These services utilize a foil method to mega-lighten up all your hair, usually some type of root smudging, toning, baby lighting and anything else that may be required. Olaplex is added into all our colors for extra care.
