The medullary index is a measurement used to differentiate between types of hair. In animal hair, the medullary index is typically greater than 0.5, indicating a wider medulla relative to the diameter of the hair shaft. In contrast, human hair usually has a medullary index of less than 0.33. Therefore, a medullary index greater than 0.5 suggests the hair is from an animal.

What is the medullary index of a human hair?
The medullary index of human hair is typically less than 0.33, which means that the diameter of the medulla is less than one-third of the diameter of the entire hair shaft. Human hair generally has a solid or absent medulla, making it distinct from the hairs of many other animals that may have a more pronounced medullary structure. This characteristic is often used in forensic science for hair identification and comparison.
