Understanding the dynamics of soft hair might shine some light on theinformation loss paradox. In this paper, we introduce a new coordinate system,dressed coordinates, in order to analyze the quantum states of Hawkingradiation as a first step toward understanding the connection between soft hairand the information paradox. Dressed coordinates can be introduced by anoperator-dependent coordinate transformation that makes the soft hair degreesof freedom apparently disappear from the metric. We show that some results ofprevious studies, such as the angle-dependent Hawking temperature and the softgraviton theorem, can be easily reproduced using these dressed coordinates.Finally, we discuss future possible applications of dressed coordinates towardunderstanding the information loss paradox.
