FAQ –Hair Tissue Mineral Analysis (HTMA)
What is Hair Tissue Mineral Analysis (HTMA)?
HTMA is a laboratory method used to evaluate the long-term mineral balance of the body and exposure to heavy metals.
Hair accumulates minerals over 8–12 weeks, making it a natural “record” of metabolic processes.
What does HTMA show?
HTMA can help assess:
- levels of macro- and trace minerals,
- long-term exposure to heavy metals,
- indicators of metabolic rate,
- stress response patterns,
- mineral balance supporting the nervous, hormonal and energy systems.
Is HTMA reliable?
Yes — as a method for evaluating long-term mineral trends and environmental exposure.
It is not a diagnostic test, but a functional biomarker that reflects mineral balance and metabolism over time.
How is HTMA different from a blood test?
- Blood shows your current state.
- Hair reflects long-term trends (8–12 weeks).
The body tightly regulates mineral levels in blood, even in deficiency.
This means HTMA can reveal imbalances that may not appear in blood tests
Can HTMA detect heavy metals?
Yes. HTMA is widely used for assessing long-term exposure to:
- arsenic,
- mercury,
- lead,
- cadmium.
Are there differences between men’s and women’s results?
Differences relate mainly to physiology (hormones, thyroid, metabolism), but reference ranges are the same for both genders.
Variability relates to certain mineral ratios (e.g., Ca/Mg, Na/K), not separate norms.
How do I prepare for the test?
- Avoid colouring your hair for at least 4–6 weeks.
- Wash hair with a simple shampoo (no conditioner, oils or masks).
- Do not use styling products on the day of sampling.
- Cut hair from the nape area, close to the scalp.
Does hair dye affect the results?
Yes — therefore we recommend:
- at least 4 weeks after your last colouring,
- or cutting an undyed section of hair if available.
How long does it take to receive results?
Standard turnaround time: 7–14 business days, depending on shipping country.
Can HTMA replace a medical diagnosis?
No.
HTMA is not a diagnostic tool. It supports:
- long-term mineral assessment,
- metabolic insights,
- evaluation of environmental exposure,
- monitoring lifestyle and dietary changes.
It works best alongside blood tests and medical consultation.
Is HTMA useful for monitoring lifestyle changes and supplementation?
Yes — one of its strongest applications.
Repeating HTMA every 4–6 months helps assess:
- effects of supplementation,
- lifestyle changes,
- improvement in mineral balance,
- reduction of heavy-metal burden.
Is HTMA safe?
Yes. It is a non-invasive test requiring only a small hair sample.

Does HTMA make sense if blood tests are normal?
Yes. Blood tests show the current state, while HTMA reveals long-term mineral trends. Chronic deficiencies or metabolic imbalances may exist despite normal blood results.
How often should Hair Tissue Mineral Analysis (HTMA) be repeated?
Most commonly every 3–6 months. This interval allows assessment of whether changes in diet, supplementation, or lifestyle affect the body’s mineral balance.
What mistakes should be avoided when interpreting HTMA results?
The most common mistakes include:
- focusing exclusively on individual elements,
- ignoring mineral ratios,
- treating HTMA as a diagnostic test rather than a functional tool.
