Abstract

Hair is one of the characteristics present in humans and it possesses several functions such as protection against external factors, producing pheromones and apocrine sweat and also thermoregulation. It is also found in crime scenes as physical evidence. Hair recovered at a crime scene often denotes that there has been some physical contact between the victim and the perpetrator which could have possibly occurred as a result of a serious or violent offence. After the hair is recovered with the appropriate procedures and submitted to the laboratory it can help provide compelling evidence placing the suspect at the scene of crime. The examination procedure explored in this study will include macroscopic and microscopic. This type of analysis has its own drawbacks which will be explored in detail as well as ways to prevent and eradicate issues such as bias and carelessness of the examiner. One of the main topics focused will be regarding the detailed comparison of the characteristics of the cuticle, cortex and medulla. Lastly, samples will be selected without the examiner’s knowledge of their source and identification of the source will be made based on the characteristics of the samples.
