  1. For hair to be considered as class evidence, it is important to collect the part of the hair that contains the root or follicle.
  2. The reason being, the root or follicle may contain DNA, which can potentially provide genetic information about the individual the hair came from. However, hair without follicles can still be useful as class evidence because it can be used to determine characteristics such as color, length, and the presence or absence of artificial treatments (like dying or perming).
  3. Class evidence isn't about linking the evidence to a single person with absolute certainty; rather, it's about narrowing down the evidence to a group of individuals who share certain characteristics.
