What is Hair Testing?

Hair is made up of keratin, a strong structural protein that comprises three parts, the medulla, the cortex, and the cuticle. Beyond its anthropological and biological meaning, this biomaterial has the ability to store what passes through the body. That’s why the courts use hair testing as a way to remove a person from suspicion or connect certain suspects with criminal activity. Forensic toxicologists are the people responsible for the analyzing of hair for the courts.
