I have an old hand made carpet that was hemed and repaired with someones hair. In korea women would weave special sandles for sickened husbands to wear for healing, made from there hair, "hairwork" is common as a form of mourning jewlery going back.hundreds of years. I know of native superstitions and practices, around hair which are quite varied, that are still followed. And so, I will state the scientific principal that one data point, is zero data points, interesting perhaps, but the very definition of inconclusive.
