HUMAN HAIR PERFORATION: AN ADDITIONAL TOOL IN FORENSIC BIOLOGY

The hair perforation is a prominent feature in several infected hairs. Different types of perforators are found in human hairs. Some of these are presented in the present study for the first time which may be proved as additional tool in hair diagnosis in forensic biology. Other structure and type of hairs, their chemical structures are also reviewed in order to consolidate important aspects of hair diagnosis.
