RESUMEN

Differential thermal and thermogravimetric analyses (DTA and TGA, respectively) of hairs at temperature range of 20 to 250 degrees C were carried out to determine the age and sex. Results of DTA and TGA unambiguously indicate that rhombic modification of sulphur (alpha-S) predominates in female hairs, whereas the monoclinal one (beta-S) prevails in male hairs whatever the age of examinees, that is, the sex can be identified with the use of these characteristics.
