a hair sample could be better described as the timeline of ur life from the moment that piece of hair started growing...
it will have trace chemicals of everything u ate or drank in that anytime.... if u took drugs or medicine it will show up... they can even know what time u took the substance from the position of the chemical in the hair sample....

for further knowledge; when somebody is suspected to have died from food poisoning,, they take the hair sample..because the poison must showup in the hair sample...same as everything else...
