Zusammenfassung:Method and apparatus for examining human hairs (1) by means of a top illumination beam (2), in which a light beam (3) reflected from the hairs (1) is registered and used for an evaluation, comprising means for scanning at least part (W) of the width (4) of a number of human hairs (1) at is least once in a line (5) with the top illumination beam (2), and a device (6) registering the reflected light beMethod for examining human hairs(1) by means of a top ilumination bean (2) , in which a light beam (3) reflected from the hairs (1) is registered and used for an evaluation. At least part (W) of a width (4) of the number of human hairs (1) is scanned at least once in a line (5) by the top illumination beam (2). The reflected ligth bean (3) produced in the process registered and used for counting of the amount of the number of hairs (1) and being evaluated and being displayed . (1). Apparatus for examining human hairs (1) by means of a top illumination beam (2) in which a light beam (3) reflected from the hairs (1) is registered and used for an evaluation, comprising means for scanning at least part (W) of the width (4) of a number of human hairs (1) at is least once in a line (5) with the top illumination beam (2), and a device (6) registering the reflected light beam (3) produced in the process continuously as proportional electrical signals (103) and a counter (71) counting the signals (103) as amount of the number of hairs (1), and an evaluator (72) evaluating the amount of the number of hairs (1) and displaying it via a display (32).
