hair evidence

Hair evidence is physical material collected from a crime scene or suspect that can provide investigative clues. Hair consists of a tough protein called keratin and may include follicle tissue, which contains DNA. Analyzing hair can help identify individuals, establish contact with a crime scene, or link a suspect to a victim. Although hair alone might not always be conclusive due to common hair types, microscopic examination can reveal details about origin (human or animal), race, or whether it’s been forcibly removed. DNA analysis from hair follicles offers the most definitive identification.
