Microscope: Place hair on wet glass slide with forceps. Cover with clear protector so the hair or fiber stays in place. Observe slide and draw. By looking at different hairs or fibers under microscopes, you can compare the slides and decide whether they are the same or not.
There are color tests that can be used for fibers but the fibers need to be stripped of their colors before the test. This is because fibers are usually dyed.
Hair : During the lab we did in class, we had to observe seven different known hair samples and we had to compare and find out which one was the closest to the unknown hair sample.
