Hair analysis is the medical examination of a hair sample. It can be hair from a crime spot examined to find out who committed the crime, or it can be hair taken from the back of your head and sent to a laboratory to check for signs of health issues.
Hair Analysis: Scientific Basis
The scientific basis of hair analysis goes like this: when new hair cells are budding in the hair follicle, they take in traces of substances going through the blood stream of the individual. As hair grows, the new cells push out the older ones, and as cells come out of the bulb, they die and harden – and thus create a long lasting record of whatever was in the blood of the person when they were forming.
