Abstract
Methods for waterless removal of sebum from a subject. Methods include contacting the hair of a subject with a heated airflow, for example, as generated by a device for waterless sebum removal. As the heated airflow contacts sebum, it warms and softens the sebum to facilitate removal of the sebum from the subject. Methods can make practical use of the Coandǎ effect to increase contact of the subject's hair with an absorbent substrate for transfer of heated sebum to the substrate during use. Methods can also utilize devices that include sensors and control circuitry for smart management of operation of the device, such as control of temperature of the heated airflow, to ensure efficacy of sebum removal without causing damage to the subject's hair.
