A fast Google find will expose all species of articles telling you exactly how you deserve to cheat a hair medicine test - and also (somewhat dubious) story of just how some have succeeded.

But which of these cheats job-related - and which don’t? We’ve put together a overview to five common methods world use to cheat the mechanism - and also how successful they yes, really are.


1. Attract a wig come cheat a hair test

Let’s confront it, most of the time it’s basic to point out a wig a mile off. They’ll regularly fit badly, fail to complement the wearer’s colouring or face hair, and also if they’re no well secured, they have actually a tendency to slip. The majority are likewise made from fabricated hair, rather than real human hair - so even if castle fool us, yes no chance they’ll fool our mass spectrometers, which review the whole chemical ingredient of the sample.

But no all wigs are created equal. If someone’s really devoted to preventing a test, they might spend thousands of pounds ~ above a bespoke, professional wig, made of human being hair. They’re lot harder come spot by eye, and our testing tools will detect them because that what they room - perfect real human hair.

That’s wherein our strict collection steps come right into play. Our chain of custody demands that someone who knows the person being experiment - a lawyer or society worker for circumstances - be present when the sample is collected. If a person turns up v a wildly various haircut to a pair of days before, they will an alert and asking some tough questions.

2. Shaving her hair off to protect against a hair test

While it’s true us can’t collect hair from a outright head, a freshly shave head ~ above the job of a hair medicine test is an ext than a little suspect. What many human being who execute this don’t realise is the in the lack of head hair, we’ll just test human body hair instead. And also because body hair grows at a slower rate than head hair, the can present a longer period of drug use. They’ve actually made their case worse.

Those who perform realise sometimes take points one step further, and remove every traces that follicular development from your body. Not only is this painful and time-consuming, the sets turn off our uncertainty radar also more. Even then, all is no lost. In instances like these, blood and urine tests can still provide an point out of current drug use, as can fingernail testing - and there’s naught to stop us from calling a topic in for a retest as soon as hair has actually grown back.

3. Bleaching hair come trick a hair test

It’s true that bleaching hair have the right to remove toxins. Just one bleach deserve to remove in between 40% and also 80% that the metabolites in a single sample through damaging the hair shaft. However, the still way that 20% come 60% the the metabolites room still there to it is in detected - and also in using LC-MS/MS to check a hair sample, they will be found.


If hair is bleaching regularly, it may be the no map of drugs can be uncovered - even if they have been supplied within the experimentation time frame. Here, again, us can quickly use body hair together a fallback - and also blood or urine tests if a subject turns up v a suspiciously blond head the hair and a fuzz-free body

4. Swapping hair samples to prevent drug use being detected

We’ve heard tales of topics attempting to steal samples as soon as we’ve taken them, and also swap them v those taken from drug-free friends. Some also wilder plans have actually been attempted - like the same twins trying to fool the device by switching areas on the work of the test. In all honesty, that won’t wash through us.


It goes ago to the chain of custody again. If the cutting of hair is a an easy process, we adhere come an incredibly stringent procedure when collecting, packaging and testing in ours labs. In short, shot swapping samples, and you’re guaranteed to fail. Whatever we carry out is subject to strictly controls that ensure the our results will wake up in court

5. Internet-bought pills or shampoos to remove drugs native hair

There are products on the industry that can penetrate within the hair shaft and also remove any type of traces that toxins. Sound too an excellent to be true, no it? That’s due to the fact that it is.

There’s no proof the these “detox shampoos” and other products have any effect whatsoever. Their sellers food on the fears and anxieties of those wait for hair testing - and their ridiculously high prices reflect this. Those who room suckered into buying will uncover themselves spending a lot of money top top a test an outcome that will be no different.

A Wiley research document from so late 2017 highlights hopeful user reviews of particular shampoos virtual - but also notes that some of those that passed after making use of such a product might simply have actually not used enough of the substance to it is in detected at its identified cut-off. Meanwhile, a further research file reveals the a solitary treatment with one particular shampoo to be not enough to reduce drug concentrations to below the cut-off.


The web is awash through stories of exactly how individuals have properly cheated a hair medicine test. While many are most likely fantasy, some might well be true - which simply serves to show how vital it is to use a professional, fully accredited testing laboratory.

The chain the custody procedures that the laboratory has in place should certain that any attempts come cheat the sample collection itself room foiled. The expert interpretation of the outcomes by the lab will take into consideration any adjust recognised in the hair’s appearance before the sample is taken. The testing technique itself additionally has a huge part to play.
