The only physical evidence the prosecution offered in 1982 was a hair analysis that was "consistent" with Broadwater. More alarmingly, the only reason the case was re-examined was the unusual fact that Sebold had written an extensive memoir of her experiences ( Lucky ), which allowed later investigators to uncover major problems with the case.
In mainstream scientific usage, hair analysis is the chemical analysis of a hair sample. The use of hair analysis in alternative medicine as a method of investigation to assist alternative diagnosis is controversial [1] [2] and its use in this manner has been opposed repeatedly by the AMA because of its unproven status and its potential for healthcare fraud.
Some of these characteristics in humans' head hair vary by race: people of mostly African ancestry tend to have hair with a diameter of 60–90 μm and a flat cross-section, while people of mostly European or Middle Eastern ancestry tend to have hair with a diameter of 70–100 μm and an oval cross-section, and people of mostly Asian or Native ...

At puberty, androgen hormones cause much of the vellus hair to turn into terminal hair and stimulate the growth of new hair in the armpit and the pubic area. In men, this ...
To enter the drug treatment system, such as it is, requires a leap of faith. The system operates largely unmoved by the findings of medical science. Peer-reviewed data and evidence-based practices do not govern how rehabilitation facilities work. There are very few reassuring medical degrees adorning their walls.
Many methods that are used in forensic science evidence have been proven to be unreliable. A lot of trials have been reviewed and testimony involving mostly microscopic hair comparison, but also bite mark, shoe print, soil, fiber, and fingerprint comparisons have been overturned because forensic analysts have provided invalid testimony at the ...
