Answer 1

It has been extremely flawed in hundreds of trials,

Step-by-step explanation:

This fact was brought up to the public by a non-profit group called the Innocence project, which created to fight for the people who were wrongfully convicted by the criminal justice system.

They provided overwhelming evidence to the point where the Bureau itself has admitted its flaw.

According to the investigation, the scientists who worked for the FBI massively overstate the scientific accuracy that they used as a basis of the hair analysis. As a result, many of the innocent people were falsely punished or even executed.
