It seems hair tests have been developed to tell just about everything a person has ingested since their last visit to the hair salon. A single strand of hair amounts to an entire biological information bank. And the longer the hair, the more information it contains. Hair grows at about 1.25cm (0.5in) a month, so analysis can span years. The Norwegian University of Science and Technology said its hair test was fair easier to carry out than taking blood and revealed far more.
This would mean doctors would now get additional information on the symptoms of our illnesses to help them diagnose our ills. Faster and earlier detection of illnesses would be forthcoming then? Should we all start keeping longer hairs? Would bald people be at a disadvantage, then? How wide-spread and advanced is this technique, and are other universities offering this course? The test should not be expensive, should it? Wonderful, the way science is developing!
