Just as Tesla re-wrote the book on cars, ColorOnly re-imagined the hair coloring process. By turning the hair dye industry on its head, ColorOnly brushed through a series of gnarly challenges and invented EMMA, the world’s first intelligent hair coloring and processing system. EMMA, which stands for Express Mixing Machine Assistant, is powered by ColorOnly’s software to precisely dispense exact hair color dyes for each client on demand. When a client buys online or walks into one of our salons, EMMA pumps out that client’s specific color request. At-home users will know that EMMA produced their hair dye the minute they placed an order, and in-salon users will save tons of time as a certified colorist collects the freshly dispensed hair color in seconds. EMMA is precise and perfect every time. Say goodbye to trial and error hair dying.
