History of Hair and Fibers

In the early 1900's microscopic examination of hair was found and very well used. A single strand of hair holds all kinds of information, it can tell you the race, sex, and the age of the person it came from. They call the scientific study of hair "trichology." Trichology got much bigger really fast after microscopic hair examination became known in the early 20th century. Professor John Glaister became a renowned resource for hair analysis information. In 1977, John Hick's laid out the groundwork for the use of hair evidence by the forensic examiner.
