Every color service includes a standard product allotment. Depending on your hair’s length, density, or the complexity of your service, additional product may be required to achieve your desired result. We use Vish, a professional precision weighing system that measures every gram of color used. Any product beyond your allotment is charged exactly by weight at service completion — you are never charged for product that wasn’t used. Before your service begins, your stylist will give you an estimated range for any additional product cost, with a spread of no more than $20.
