forensic hair analysis

Forensic hair analysis involves examining hair samples collected from crime scenes or individuals to gather information about their origin, timespan, and possible connections to a suspect or location. Experts analyze physical characteristics such as color, thickness, and structure under a microscope, and may perform chemical tests to detect substances like drugs or toxins embedded in the hair. While it can help identify if a hair matches a particular person or environment, it is generally considered one small piece of evidence within a broader investigation, rather than definitive proof on its own.
