Ethyl glucuronide (EtG) is a minor hepatic metabolite of ethanol
and is used as a marker of ethanol consumption [1,2].
Recently,Sporkert et al.
[3] reported about positive EtG hair testings caused
by hair treatment with an EtG containing herbal hair lotion.
The present study aimed to assess whether this has been a single
observation for that specific hair lotion or whether EtG appears
more frequently in commercial hair care products.
