The system disclosed consists of a rigid hollow microcylinder of variable diameter and height ranging from 20 microns to 3 mm, made of a material chosen from the malleable metals and metal alloys, possibly patinated or tinted. The system can be used to determine the number of deracinated hairs and/or the distance of the microcylinder from the scalp and to calculate the percentage loss and/or regrowth of hair. The microcylinder (1), several hairs (2), the scalp (3), and the connecting thread (4) are shown.
