As head hairs are routinely compared in a forensic laboratory, it is important to obtain suitable known samples from suspects and victims and possibly from other individuals (elimination samples). The known sample should contain a random sampling of hair from different areas of the scalp. The number of hairs required for a meaningful comparison may vary depending on the uniformity of characteristics present in the hairs from an individual. Because this is not known when the hair sample is taken, obtain at least 25 full-length hairs. This hair sample should include both plucked and combed hairs, packaged separately.
