A device (1.1) for the radiation of scalp hair (2) using infrared radiation (10.3),wherein the infrared radiation (10.3) is generated by at least one linear-shapedinfrared lamp (3.1) with a reflector system (4). In a first exemplary embodiment,a first reflector (6.1) is allocated to the infrared lamp (3.1) on the longitudinalside, wherein the infrared lamp (3.1) basically forms an optical collectionline of the first reflector (6.1). The first reflector (6.1) with a first reflectionside (9.1) and a second reflector (6.2) with a second reflection side (9.2) areplaced facing each other, wherein the infrared lamp (3.1) is enclosed by the firstand the second reflector (6.1, 6.2), by at least 360° altogether. Thereis a third reflector (6.3) arranged with a third reflection side (9.3), whereina first infrared radiation output (10.1) of the first reflection side (9.1) impactsthe second reflection side (9.2), wherein a second infrared radiation output(10.2) of the second reflection side (9.2) impacts the third reflection side(9.3), and wherein a third infrared radiation output (10.3) of the third reflectionside (9.3) radiates the scalp hair (2).
