HUMAN HAIR IS ONE OF THE MOST FREQUENTLY FOUND PIECES OF
EVIDENCE AT THE SCENE OF A VIOLENT CRIME. IT CAN PROVIDE A LINK
BETWEEN THE CRIMINAL AND THE CRIME.
HAIR IS A BIOLOGICAL EVIDENCE AND SCIENTIFIC STUDY OF HAIR IS
CALLED “TRICOLOGY” AND WHEN THIS STUDY USED IN CRIMINAL
JUSTICE DELIVERY SYSTEM IS TERMED AS “FORENSIC TRICOLOGY”.
HAIRS ARE UBIQUITOUS TRACE MATERIAL IN FORENSIC INVESTIGATION.
HAIR CAN EASILY BE LEFT BEHIND AT THE CRIME SCENE. IT CAN ADHERE
TO CLOTHS, CARPETS, SURFACE, WEAPON, VEHICLE AND MANY OTHER
SURFACES AND BE TRANSFERRED TO OTHER LOCATION AND CRIME SCENE
DUE TO CONTACT.
HAIR IS THE MOST COMMONLY FOUND PHYSICAL EVIDENCE IN CRIME
SUCH AS SEXUAL OFFENSES, HOMICIDAL ASSAULTS, ROAD ACCIDENTS.
HAIR DOES NOT DECOMPOSE EASILY. HAIR CONSISTS OF TWO PARTS
THAT ARE FOLLICLE AND SHAFT.
