| 1. A hair sensor for detecting a sliding sound of hair in order to estimate hair characteristics, comprising:
a sliding element capable of sliding on hair;
a housing including a microphone provided therein;
a diaphragm on which the sliding element is located to erect, wherein the sliding element and the diaphragm are arranged to
allow a sliding sound caused by the sliding element to be transmitted to the microphone as vibration and to attenuate vibration
transmitted from outside of the diaphragm to the microphone; and
the diaphragm is configured so as to be in direct contact with said microphone so as to allow a sliding sound caused by the
sliding element to be transmitted to the microphone as a vibration.
