THE BLOG - Musings on living well for longer

Recently I took the plunge and paid for a hair analysis sample to determine what, if anything, was deficient in my body or any external factors that may be preventing my wellbeing being optimised. The results were fascinating, but then I dug a little deeper to  check the validity of the findings. Some aspects were disappointing, with little or no reliable evidence to back up the individual aspects of the report I received. I have written this blog to help you become more aware, more informed and armed with the right questions before you part with your hard earned cash. 

Have you ever been offered a test that promises to reveal what your body really needs?

Perhaps it claims to identify hidden toxins, nutritional deficiencies, food intolerances or even the effects of electromagnetic frequencies. It sounds fascinating, doesn't it? A simple test, a beautifully presented report and suddenly a whole new understanding of your health. But here's a question we don't always ask:

How do we know the test is actually measuring what it claims to measure?

When curiosity meets a convincing sales pitch

I recently attended a wellbeing retreat and decided to pay extra for a personalised hair analysis. The report was impressive. Colourful charts, scientific terminology, individual recommendations and a 90-day plan designed to optimise my wellbeing. It highlighted potential concerns about toxic metals, electromagnetic interference and various nutritional requirements. I was quite surprised about the nutritional deficiencies as I have an extremely healthy diet and habits around eating for optimised health.

As someone with a clinical background and a strong interest in holistic wellbeing, I was intrigued. But when I started looking more closely at the science and company behind the analysis, I found myself asking some rather uncomfortable questions.

Could a few strands of hair really reveal all this information? And, more importantly, where was the independent evidence that the testing method worked?

Not all hair tests are created equal

Hair analysis isn't automatically unreliable. In specialist circumstances, properly conducted laboratory analysis can provide useful information about exposure to certain substances, including methylmercury. But there is a huge difference between a laboratory measuring the concentration of a specific chemical and a wellness device claiming to identify dozens of health concerns from the body's supposed energetic signals.

Some commercial hair-testing systems use terms such as bioresonance, frequency analysis or epigenetic mapping. These phrases sound wonderfully scientific and some of the underlying scientific fields are entirely legitimate. However using scientific terminology doesn't automatically make a particular test scientifically valid. For example, epigenetics is a genuine area of biological research. That doesn't mean a device marketed as an epigenetic hair scanner can accurately assess your vitamin levels, toxic-metal burden or immune function.

The crucial question isn't whether the technology sounds impressive. It's whether the specific claims have been independently tested and validated.

What about toxins and electromagnetic exposure?

On my report there were two findings that particularly caught my attention. Heavy-metal exposure and electromagnetic exposure.

Heavy-metal exposure is a genuine health concern in certain circumstances. But identifying harmful exposure usually requires appropriate clinical assessment and validated testing, often involving blood or urine samples. A report that identifies a toxic-metal problem without telling you which metals were measured, their concentrations or the relevant reference ranges should prompt further questions. My report contained none of these.

Electromagnetic exposure is even more problematic.

We are surrounded by electromagnetic fields from electrical appliances, mobile phones and other technologies. These fields can be measured using appropriate equipment. However, there is currently no established clinical evidence that analysing a hair sample can reliably identify an individual's electromagnetic exposure or the health effects attributed to it. That doesn't mean science has answered every question about our environment. It means we must distinguish between something being scientifically possible, something being actively researched and something being demonstrated by reliable evidence.

Seven questions to ask before paying for a wellness test

Here's my checklist. You might want to save it for your next retreat, wellness consultation or health-testing appointment.

1. What exactly is being measured?

Ask whether the test measures a physical substance, a biological marker or an interpreted signal. These are very different things.

2. Is the test scientifically validated?

Can the provider show independent, peer-reviewed research demonstrating that this particular testing method accurately identifies what it claims?

Testimonials and company-produced research aren't the same as independent validation.

3. Is the laboratory appropriately accredited?

Ask which laboratory performs the analysis and whether it holds relevant accreditation, such as ISO 15189 or ISO/IEC 17025, for the specific tests being offered.

 Note:  A device having a CE mark or electrical safety certification does not automatically establish clinical accuracy.

4. Would the test give the same result twice?

Reliability matters. If the same sample were tested again under identical conditions, would the findings be consistent?

A test that cannot demonstrate reproducibility deserves particular scrutiny.

5. Will I receive actual measurements?

For a test claiming to identify toxic metals or nutrient deficiencies, ask about concentrations, units, reference ranges and how results are interpreted.

Colourful charts and priority scores are not substitutes for validated measurements.

6. Could the results lead to unnecessary treatment or expense?

Be especially cautious if a test identifies numerous problems and the provider then recommends purchasing supplements, detox products or repeat assessments. A financial incentive doesn't automatically make advice wrong, but it does make transparency particularly important.

7. What would a qualified healthcare professional make of the findings?

If a test suggests a significant health problem, ask whether the result can be confirmed using an established clinical method.  It is also important that you never stop prescribed medication or undertake potentially harmful detoxification treatments on the basis of an unvalidated wellness test.

Seven warning signs worth remembering

Be cautious when a provider:

• Claims one simple test can identify an unusually wide range of unrelated health problems.

• Uses scientific-sounding language without explaining the actual measurement method.

• Cannot provide independent validation studies.

• Provides coloured scores but no meaningful measurements or reference ranges.

• Suggests that everyday electromagnetic exposure is harming you based on a hair sample.

• Recommends expensive supplements or repeat testing to correct the reported problems.

• Explains inconsistent results as evidence that your body's energy or epigenetic environment is constantly changing, rather than demonstrating the test's reliability.

None of these automatically proves dishonesty. But they are good reasons to ask more questions before spending your money.

Does this mean we should dismiss holistic wellbeing?

Absolutely not.

I'm passionate about the relationship between nutrition, movement, sleep, stress, our environment and how we feel. I believe there's enormous value in taking a whole-person approach to health and wellbeing. But being holistic doesn't mean abandoning scientific scrutiny. In fact, I would argue the opposite.

The more we care about our wellbeing, the more important it becomes to understand which interventions are supported by evidence and which remain speculative. We can embrace complementary approaches, explore emerging research and remain open-minded without accepting every claim made in the name of wellness.

My biggest takeaway

I don't regret being curious, but I do wish I'd asked more questions before paying for the test.

The experience reminded me how easy it is to be persuaded by sophisticated presentation, reassuring language and the promise of personalised answers.

• A beautiful report can feel authoritative.
• A complicated chart can look convincing.
• And a recommendation described as being uniquely tailored to our body can be very appealing.
• But none of those things tells us whether the findings are accurate.

Before investing in any health or wellness test or intervention, ask yourself: am I paying for reliable information, or simply an interesting interpretation?

Sometimes the most empowering thing we can do for our wellbeing isn't to buy another test, it's to ask a better questions.
