HUMAN HAIR: A STRONG FORENSIC EVIDENCE

Microscopic analysis of human hair can be a powerful evidence in the field of forensic science. Examination of different characteristics of hairs under a microscope are studied usually for comparing hair taken from a crime scene and hair taken from a suspect. Hair found can link the crime scene to the suspect and a victim. The visual characteristics of hair are observed as color, length, texture and type. In microscopic analysis, more detailed hair characteristics are noticed that finally help to establish a correlation between a suspect and a crime scene or a suspect and a victim. [1, 2]. When the hair is present with the root follicle than DNA profiling can be done but if hair is present without root follicle than profiling is done by mitochondrial DNA.
