  • Publication number: 20100224205
    Abstract: An apparatus for modifying a keratinous surface having an applicator, a first modification agent; a sensor; and a CPU. The sensor reads the properties of a small portion of the keratinous surface, the readings are transmitted to the CPU, and the CPU compares the readings to a predetermined baseline value. The CPU then calculates the variance between the reading and the baseline value. When that variance exceeds a predetermined threshold the CPU sends a signal to the applicator which is activated to apply a portion of the first modification composition to the same portion of the keratinous surface that had the reading with a variance above the threshold value.
