A wearable eyebrow-irradiating device includes a main irradiation body, a circumferential light-shielding lining and a fastening headband. The main irradiation body, worn on user's head, has at least one lighting component for projecting respective eyebrow-growth stimulating beams onto corresponding eyebrow-growing zones upon when the main irradiation body is fitted onto the head. The circumferential light-shielding lining, mounted fixedly at the main irradiation body by surrounding the lighting component, is to shield the eyebrow-growing zone, so that an eye can be isolated from the neighboring eyebrow-growing zone. The fastening headband, connecting the main irradiation body, is to wear the main irradiation body tightly onto the head, and to elastically deform the circumferential light-shielding lining so as to completely shield the eyebrow-growing zone and thus to prevent the eyebrow-growth stimulating beam from irradiating the eye.

A pulsed laser skin treatment device is for laser induced optical breakdown of hair or skin tissue. The device has a light exit window to be placed against a surface to be treated such as skin during use. A feedback system is used for determining a state of contact between the light exit window and the surface. To this end the feedback system is capable of detecting a feedback signal representative for the state of contact. If the feedback signal or the state of contact is such that the risk of skin surface or device damage by the device operation is too high, the user or the device has a way to interrupt the treatment or to reduce light output to reduce or eliminate this risk.

The present invention is directed to a method for simultaneously treating alopecia and achromotrichia comprising topically administering to a human in need thereof an effective amount of a composition comprising a compound of formula (II)
