But i beg your pardon of this cheats work - and also which don’t? We’ve placed together a overview to five common methods people use come cheat the system - and also how successful they yes, really are.


1. Wearing a wig come cheat a hair test

Let’s challenge it, most of the time it’s simple to clues a wig a mile off. They’ll frequently fit badly, failure to complement the wearer’s colouring or facial hair, and if they’re no well secured, they have a tendency to slip. The majority are likewise made from fabricated hair, quite than real human hair - so also if they fool us, yes no possibility they’ll fool our mass spectrometers, which read the whole chemical composition of the sample.

But no all wigs are produced equal. If someone’s really devoted to staying clear of a test, they could spend hundreds of pounds on a bespoke, professional wig, made of person hair. They’re lot harder come spot through eye, and our testing equipment will finding them because that what they space - perfect real human being hair.

That’s whereby our strictly collection actions come right into play. Our chain the custody requirements that someone who knows the human being being tested - a lawyer or society worker for circumstances - be present when the sample is collected. If a human turns up through a wildly various haircut to a pair of work before, they will notice and questioning some difficult questions.

2. Shaving her hair turn off to avoid a hair test

While it’s true we can’t collect hair native a fully head, a freshly shaved head ~ above the work of a hair drug test is more than a small suspect. What many civilization who execute this don’t realise is that in the absence of head hair, we’ll simply test body hair instead. And also because body hair grows at a slower price than head hair, it can show a longer duration of medicine use. They’ve in reality made their case worse.

Those who carry out realise occasionally take points one action further, and also remove all traces the follicular growth from their body. Not only is this painful and time-consuming, that sets turn off our hesitation radar even more. Even then, all is not lost. In instances like these, blood and also urine tests deserve to still offer an indication of recent drug use, as have the right to fingernail testing - and there’s naught to prevent us indigenous calling a subject in because that a retest once hair has grown back.

3. Bleaching hair to trick a hair test

It’s true the bleaching hair deserve to remove toxins. Simply one bleach deserve to remove in between 40% and 80% that the metabolites in a single sample by damaging the hair shaft. However, the still means that 20% come 60% that the metabolites are still over there to be detected - and in utilizing LC-MS/MS to check a hair sample, they will be found.


If hair is bleached regularly, it may be the no map of drugs have the right to be uncovered - even if they have actually been provided within the experimentation time frame. Here, again, we can easily use human body hair as a fallback - and blood or pee tests if a subject turns up with a suspiciously blond hair head that hair and a fuzz-free body

4. Swapping hair samples to avoid drug usage being detected

We’ve heard story of subjects attempting come steal samples once we’ve take away them, and also swap them v those taken native drug-free friends. Some also wilder plans have actually been attempted - like similar twins trying come fool the device by switching areas on the work of the test. In every honesty, that won’t wash v us.


It goes back to the chain the custody again. If the cut of hair is a basic process, we adhere to an extremely stringent process when collecting, packaging and also testing in our labs. In short, shot swapping samples, and also you’re guaranteed to fail. Every little thing we execute is topic to strict controls the ensure the our outcomes will stand up in court

5. Internet-bought pills or shampoos to eliminate drugs from hair

There are assets on the market that can penetrate inside the hair shaft and remove any traces that toxins. Sound too an excellent to be true, doesn’t it? That’s due to the fact that it is.

There’s no proof that these “detox shampoos” and also other commodities have any kind of effect whatsoever. Your sellers food on the fears and anxieties the those waiting for hair experimentation - and their ridiculously high price reflect this. Those who space suckered right into buying will discover themselves safety a the majority of money ~ above a test an outcome that will be no different.

A Wiley research file from so late 2017 highlights positive user reviews of certain shampoos digital - but likewise notes that few of those who passed after making use of such a product may simply have not used sufficient of the problem to be detected at its characterized cut-off. Meanwhile, a further research document reveals that a solitary treatment with one details shampoo to be not enough to mitigate drug concentration to listed below the cut-off.


The internet is awash v stories of just how individuals have efficiently cheated a hair drug test. While many are most likely fantasy, some might well it is in true - which just serves to show how an important it is to usage a professional, completely accredited testing laboratory.

The chain that custody processes that the laboratory has in location should ensure that any type of attempts to cheat the sample repertoire itself space foiled. The expert interpretation the the outcomes by the lab will take into factor to consider any adjust recognised in the hair’s appearance before the sample is taken. The testing method itself also has a huge part to play. LC-MS/MS trial and error is very accurate and sensitive, specific and thorough: even if it’s not visually evident that a donor has treated their hair or is put on a wig, the test will pick the up.
