TOKYO -- L'Oreal Japan has developed a way to represent the condition of hair in sound so that salon customers can "hear" damage and the restorative effect of treatment.
The Japanese arm of French cosmetics company L'Oreal plans to commercialize a device based on the technology next year.
A sensor is run through the hair from root to tip, measuring friction and collecting data that a proprietary algorithm converts into music. Severely damaged hair is represented by rhythmically edgy music, while silky hair brings out serene sound.
While the condition of hair can already be ascertained visually and by running fingers through it, L'Oreal Japan sees music as an easier way to convey the information. It envisions salons using the device to demonstrate the effectiveness of hair treatment to customers.
