Hair Analyisis

hair structure:

hair is composed mainly of keratin and contains a cuticle, medulla, and cortex. the cuticle is the layer on the outside edges of the hair, the medulla the middle(usually a dark line) of the hair, and the cortex is everything in between. hair also contains certain characteristics depending on the type of person. the lengths, straightness, thickness, color, shape, line in the middle, and texture all rely of either race or gender. for instance, an Asian hair is typically dark brown with an even darker brown stripe down the middle while a white male may have more of a teal color with a brown stripe in the middle.

hair transfer:

hair is a very good way of catching a criminal by linking the hairs/ fibers found on his/ her shirt that match those of which a murdered victim or missing person was wearing. the transfer of hair could result from a struggle that the criminal got into with the victim and hair was left on their clothes. another place where hair evidence can be found is in the home/ car of the suspect where the victim might have been. this can also work vice-versa by seeing if there was anyone making contact with or at the house/ in the car of the victim around the time of the crime.
