Embodiment Construction
[0012] figure 1 Shown is a basic embodiment 100 of a hair care appliance comprising two jaws 101 hinged to grip hair tresses. Each jaw comprises a heat source 103 formed, for example, of a hot plate heated directly or indirectly to a first temperature T1 (eg, 120° C.), which is lower than the critical temperature Tc for stratum corneum damage. Each jaw includes a radiation source (represented by a black dot 102) formed by, for example, a continuous wave (CW) pulsed laser source or an intense pulsed light (IPL) device with a low-pass filter for emitting from 400 nm to 600 nm, preferably In the wavelength range of 450nm to 550nm, the radiation source selectively heats the cortical layer to a second temperature T2 of about 170° C., which is high enough for modeling, for a duration of about milliseconds to seconds . Depending on the treatment area and the number of hairs between the jaws, a laser array may also be used. The pulse duration of the laser pulse can be chosen to be ...
