Tracking Where You’ve Been via Hair Samples

Yes, it’s all very CSI, but it’s real. In fact the article from researchers at the University of Utah published the article in The Proceedings of the National Academy of Science. The bottom line, the amount of hydrogen and oxygen isotopes in your hair reflect where you’ve been. So, after analysis in a mass spectrometer the “fingerprint” of your hair is matched to a map that shows, regionally, where you’ve been. Mostly, the impact comes on differences in the water you drink, though there are other factors. And, since hair is a record of your diet, the longer the hair, the further back in time your location can be traced.
