According to an aspect, there is provided a personal care device () for performing a light-based hair removal or photo-epilation operation on a body of a subject. The personal care device () comprises a housing () that includes a first window or opening (), a light source configured to generate light to perform the light-based hair removal or photo-epilation operation, wherein the light source is arranged in the housing such that light emitted by the light source illuminates a part of the body, a receiving member in or on the housing () for receiving and retaining a consumer electronic device () in or on the personal care device (), and an optical system () in the housing () for enabling an imaging unit () of a consumer electronic device () retained in the recess () to obtain images of a part of the body via the first window or opening ().

Personal care device configured to perform a light-based hair removal

A hair care device () comprises a heat source () for heating hair up till a first temperature that is no more than 150&#xb0; C. (and thus lower than a critical temperature at which hair cuticle damage will occur), and a radiation source () for&#x2014;in combination with heat from the heat source ()&#x2014;selectively heating a hair cortex to a second temperature exceeding the first temperature and sufficiently high for hair styling.

Hair care device

In a hair styling device (), a light emitting diode () is configured to deliver optical energy to hair, wherein an energy fluence of the optical energy is between 0.5 and 9 J/cm, and more preferably between 1 and 5 J/cm. The light emitting diode () is pulse-driven, and a pulse width of the optical energy is at least 50 ms. An output wavelength of the optical energy may be between 400 and 900 nm. The pulse width of the optical energy is preferably between 50 and 300 ms. The hair styling device () may comprise an optical shield () configured to block stray light during light exposure of the hair. An inner surface of the optical shield () may be reflective and/or may have a parabolic shape. The optical shield () may be movable between an open position in which a lock of hair can be placed in the hair styling device () while the optical energy is not applied, and a closed position in which light is prevented from escaping the hair styling device () while the optical energy is applied to the hair. The hair styling device may be a hair straightener having opposing first and second straightening surfaces, of which at least the first straightening surface comprises the light emitting diode (), and at least the second straightening surface is arranged for reflecting light from the light emitting diode ().
