Answer to Question 1

A criminalist first compares the color and diameter of the fibers. Other morphological features that may aid in the comparison are lengthwise striations (lined markings) on the surface of some fibers and the pitting of the fiber's surface with delustering particles added in the manufacturing process to reduce shine. The cross-sectional shape of a fiber may also help characterize the fiber.

Answer to Question 2

Forensic hair comparisons generally involve either head hair or pubic hair.
