Does having bulimia affect an alcohol hair test?

No.


As the hair grows, it absorbs special markers called fatty acid ethyl esters (FAEEs) and ethyl glucuronide (EtG) into its structure, which remain in the hair indefinitely. These markers are only produced when there is alcohol in the bloodstream, such that the more markers there are, the more alcohol you have consumed.

No matter how much you puke, there'll be alcohol already in your system.

Also, I'm not sure if it's accurate or not but it's rumored that bulimia and anorexia can be determined by hair tests.
