L'Oreal introduced Colorsonic, a device for self-coloring hair
The device looks like a hair dryer-brush or a curling iron. In its lower part is a cartridge containing the desired mixture for coloring.
With Colorsonic, you can choose from 40 colors, and then the gadget itself will mix the necessary ingredients. After that, you need to start combing your hair from root to tip.
At this time, the device will distribute the prepared dye and developer evenly through special nozzles, which move more than 300 times per minute at a certain angle. After 30 minutes, hair can be rinsed and styled.
