    TLDR Caffeine in hair might help identify people, but it's not always reliable.
    The study explored the potential of using caffeine analysis as a method for forensic hair discrimination. It investigated whether caffeine levels in hair could be used to differentiate between individuals in forensic contexts. The research suggested that caffeine could be a viable marker due to its widespread consumption and incorporation into hair. However, the study acknowledged limitations, such as variability in individual caffeine metabolism and external contamination, which could affect the reliability of this method for forensic purposes.
