1. A hair treatment device comprising:
a device body;
a first sensor arranged in or on the device body, the first sensor configured to detect a hair condition parameter;
a second sensor arranged in or on the device body, the second sensor configured to detect movements and location changes of the device body; and
an electronic circuit device arranged in or on the device body,
wherein the electronic circuit device is coupled to receive the detected hair condition parameter from the first sensor and the detected movements and location changes from the second sensor,
wherein the electronic circuit device is configured to control a hair treatment parameter and to dose a hair treatment agent based on the received detected hair condition parameter, and
wherein the electronic circuit device is further configured to (i) determine a spatial position of the device body and a speed of the device body based on the received movements and location changes of the device body, (ii) determine, based on the determined spatial position of the device body, which hair regions have already been treated with the hair treatment device, and (iii) transmit data indicative of the hair regions that have already been treated; and
a display device in operable communication with the electronic circuit, the display device configured to receive the data transmitted by the electronic circuit and, in response to receiving the data, to display at least the hair regions that have already been treated.
