Abstract

The invented device for hair-care consists of an applicator (1), which is equipped with at least one print-board (6,7), upon which semiconductor-diodes (LED) or laser-diodes (8) are placed. The semiconductor-diodes (LED) and the laser-diodes radiate light with a wavelength between 350 and 1200 nm. Further, the applicator (1) contains one or more plain transmitter-coils (transducers) (3) for the emission of pulse-shaped electromagnetic radiation. It can be equipped with an IR-heating element and a ventilator to produce a warm air stream. The applicator (1) can be formed as a hood (2) or designed as a plainer surface applicator consisting of one or more parts, in the latter case the parts being connected with moveable joints. The applicator can also be designed as a hand applicator. In this case it resembles an ordinary hand-held hair drier, consisting of an almost cylindrical tube with a rectangular handle.
