People will do all sorts to avoid a hair drug test. Shaving their heads, bleaching their hair. But while these tactics may well mean that head hair can’t be tested, they won’t escape that easily.
In these cases, we’ll offer the client two options: body hair drug tests, or fingernail drug testing. While we’ve been doing the latter for over seven years, with several hundred cases on our records, it’s become far more popular in recent months. So much so, in fact, that our own Lolita has contributed to a joint research paper on whether there are significant differences between hair and fingernail test results.
