Abstract
Hair is a protein filament that grows out of the follicles of mammalian dermis. Hair is made of a tough protein called keratin and a colouring protein called melanin. Hair is also one of the most common biological evidence found at a crime scene and it is ac-counted as a class evidence. We can easily use hair to solve the question of who committed the crime as hair helps in individual-ising a person. From the root of the hair we can get nuclear DNA (Deoxyribose nucleic acid) and from the shaft of the hair we can get mitochondrial DNA. We can also use hair to find out the race and individualistic characteristics of persons. In this study, an effort has been made to distinguish between the morphometric features of hair from the different regions of India. To do this, India was divided into six regions that included the north, south, west, east, central and northeast. Fifty hair samples from each region were collected and morphological and metric features were estimated and compared. This study was conducted as there is a lack of region specific characteristics to identify people of different regions of India through hair.
