1. A hair treatment device, comprising:
a device body;
at least one sensor arranged in or on the device body, the at least one sensor configured to detect a plurality of hair condition parameters and a position of the device body; and
an electronic circuit device arranged in or on the device body,
the electronic circuit device coupled to receive the detected plurality of hair condition parameters and the position of the device body from the at least one sensor and to determine, from the detected plurality of hair condition parameters, a degree of hair damage,
wherein the electronic circuit device is configured to control at least one hair treatment parameter based on the determined degree of hair damage and to dose at least one hair treatment agent based on the determined degree of hair damage and dependent on the position of the device body, and
wherein the at least one sensor further includes at least one of a microphone or a tensile force gauge.
