Method 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. At least part (W) of the width ( 4 ) of a number of human hairs ( 1 ) is scanned at least once in a line ( 5 ) by the top illumination beam ( 2 ). The reflected light beam ( 3 ) produced in the process being registered and used for counting of the amount of the number of hairs ( 1 ) and being evaluated and being displayed. 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 the number of human hairs ( 1 ) at 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 ).
