The statement that is necessary to obtain 25 to 50 hairs from this woman "as hair differs from one person to the next."
What are hair?
Hair is a protein filament that grows from dermal follicles. Hair is one of the distinguishing features of mammals.
Hair samples are a significant resource in forensic examination of crime scenes, often offering valuable information that might lead to the identification of a suspect or victim. Because hair varies from head to head, 25 to 50 hair samples are required. Not all of them will look the same on a person's head.
The root is required to extract DNA from the sample, and the root might also reveal whether or not there was a struggle. Assume the women's hairs are microscopically comparable to the hairs obtained at the murder scene, with no significant variances.
