Devices for waterless sebum removal

Abstract

A device(9) for waterless removal of sebum from a subject (9d). The device (9) includes a head (7a) having an air duct therein and an air vent (8f, 8e) fluidly connected with the air duct of the head (7a). The air duct and the air vent (8f, 8e) of the head (7a) are configured for passage of a heated airflow therethrough, as the heated airflow contacts sebum, it warms and softens the sebum to facilitate removal of the sebum from the subject (9d). The device (9) can make practical use of the Coandǎ effect to increase contact of the subject (9d)'s hair with an absorbent substrate for transfer of heated sebum to the substrate during use. The device (9) can also include sensors and control circuitry for smart management of operation of the device (9), such as control of temperature of the heated airflow, to ensure efficacy of sebum removal without causing damage to the subject (9d)'s hair.
