    Everything that you could possibly want to know about analysis and collection of hair can be found here:

    U.S. Department of Health and Human Services, Centers for Disease Control and Prevention, Agency for Toxic Substances and Disease Registry (ATSDR)

    The mission of the Agency for Toxic Substances and Disease Registry (ATSDR), as an agency of the U.S. Department of Health and Human Services, is to serve the public by using the best science, taking responsive public health actions, and providing trusted health information to prevent harmful exposures and disease related to toxic substances.

    ATSDR is directed by congressional mandate to perform specific functions concerning the effect on public health of hazardous substances in the environment. These functions include public health assessments of waste sites, health consultations concerning specific hazardous substances, health surveillance and registries, response to emergency releases of hazardous substances, applied research in support of public health assessments, information development and dissemination, and education and training concerning hazardous substances.

    What part exactly? Maybe this will answer.

    If the root is still on the hair (looks like a small piece of skin), an entire DNA profile can be done. If not, I believe the hair is chemically cleaned to remove anything that might be on the hair. It is then ground up in something like a mortar and pestle (like pharmacies used to use) then dissolved in a different chemical (don't remember which) and they can extract what is called Mitochondrial DNA (sp?). That is a form of DNA that is passed only from the mother. If that were necessary, investigators would at least be able to tell if a suspect was the child of a particular woman, providing of course, they have a DNA sample from the mother or a sibling.

    Different analysis can be done depending on what you want to identify.

    Chemicals can be used to detect the presence of other chemicals (drug testing)

    Visual inspection under a microscope can be used for identification of the hair (medulla, pigment, scale pattern, etc) for forensic evaluation.

    DNA testing may be possible if there is flesh attached to the root.
