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 ...

Abstract

A hair care device (100) comprises a heat source (103) for heating hair up till a first temperature that is no more than 150 DEG C (and thus lower than a critical temperature at which hair cuticle damage will occur), and a radiation source (102) for in combination with heat from the heat source (103) selectively heating a hair cortex to a second temperature exceeding the first temperature and sufficiently high for hair styling.

Description

technical field [0001] The present invention relates to a hair care device. Background technique [0002] FR2979202 discloses a hair styling heating device for e.g. detangling hair, which has an arm comprising a clamping portion comprising a single red (wavelength between 620nm and 800nm) and Infrared (wavelength above 780nm) ray emitter, the treatment plate is placed in contact with the hair. This is based on the idea that treating the hair substantially separately from the radiation (i.e., before or after the radiation) by contacting the hair with a hot surface makes it possible to enhance the protection of the hair, compared to the substantially simultaneous treatment with heat contact and radiation, to increase The brightness of the hair. The temperature of the treatment plate is between 160°C and 240°C, preferably between 180°C and 220°C. [0003] Many women are primarily concerned with hair damage from styling and are sometimes dissatisfied with the results they get...
