As I understand it, the dna is usually sourced when the hair root is intact as that contains skin cells. Hair itself is keratin and can be type matched - eg coarseness, colour, texture, tested for chemicals (eg environmental, dyes, medication, recreational) which all amount to circumstantial evidence but to get a DNA match actual cells would be required. Assuming the donation is the result of a haircut and not epilation or scalping - she’s probably in the clear.

As a frequent watcher of Forensic Files, I concur. There is no DNA to match in hair. Donated hair is also washed in these programs, so any other sources of DNA, other than an attached root, is going to be washed away.

As someone who has watched Forensic Files and rewatched almost every episode multiple times, I would slightly disagree. It’s true that hair without the root usually doesn’t contain nuclear DNA that can be used to directly match a person. However, hair shafts can still contain mitochondrial DNA.

Mitochondrial DNA is inherited through the maternal line and can sometimes be recovered even when the root is missing. While it’s not as specific as nuclear DNA and usually can’t identify a single individual, it can still help investigators narrow things down to a maternal lineage.
