What Does a Hair Mineral Analysis Show?

If you have recently received a hair mineral analysis report - or you're deciding whether the test is worth doing - you probably want one thing: to understand what it actually tells you. This guide explains what the test measures, what the numbers and ratios on the report mean, and where it fits alongside blood testing.

Hair mineral analysis, also known as Hair Tissue Mineral Analysis (HTMA), is a laboratory test that measures the levels of minerals and selected heavy metals stored in a small sample of hair taken close to the scalp.

Unlike a blood test, which captures what is circulating in your bloodstream at one moment, hair may reflect mineral exposure and storage patterns over roughly the previous three to four months. Hair grows about 1 cm per month, so a sample creates a kind of historical record of certain elements present during that period.

A report generally covers two categories.

Nutrients your body needs for normal function - for example calcium, magnesium, zinc, copper, selenium, iron, chromium, manganese, potassium, and sodium. These play roles in energy production, hormone function, immune health, fertility, bone health, and nervous and muscle function.

The test may also screen for exposure to selected heavy metals such as mercury, lead, arsenic, cadmium, aluminium, and nickel. The purpose is not to diagnose poisoning, but to flag patterns that may warrant further investigation.

Most reports give you three things, and understanding all three is the key to interpreting the report correctly.

Individual mineral levels - the measured concentration of each mineral.

Reference ranges - the laboratory's comparison ranges, used to show whether a result sits within, above, or below expected limits.

Mineral ratios - relationships between minerals, which some laboratories calculate because the balance between minerals can be as informative as any single value. Commonly reported ratios include:

• Calcium-to-magnesium (Ca/Mg)
• Sodium-to-potassium (Na/K)
• Zinc-to-copper (Zn/Cu)

These ratios are widely used within nutritional and functional medicine to explore broader patterns of mineral balance, rather than to diagnose a specific condition.

This is one of the most common questions - and the honest answer is nuanced. Hair mineral analysis does not directly diagnose a vitamin or mineral deficiency. What it can do is highlight mineral patterns that suggest possible imbalances or altered mineral status. For example, low zinc patterns may be associated with hair-health concerns, and low magnesium patterns may be worth assessing further. This is exactly why the test is most useful alongside blood testing rather than on its own.

Yes. HTMA may identify elevated levels of metals such as lead, mercury, arsenic, cadmium, and aluminium. Any abnormal finding should be interpreted carefully and in context - alongside your symptoms, occupational and environmental exposure, and medical history - and may prompt further investigation rather than a diagnosis on its own.

Patients often ask which one they should have. They answer different questions, so it isn't really a competition.

A blood test shows what is circulating right now - for example iron, ferritin, vitamin D, thyroid hormones, testosterone, or inflammatory markers. A hair mineral analysis may give insight into longer-term mineral exposure, storage patterns, selected heavy-metal exposure, and mineral-balance trends. Most clinicians treat the two as complementary: hair for longer-term trends, blood to confirm and expand on current status. For a fuller picture, hair analysis is often paired with a comprehensive vitamins and minerals blood profile.

Hair mineral analysis is generally not offered as a routine NHS test; it is usually accessed privately, as part of nutritional, functional, or preventative health assessment. If you're considering it, you can arrange the test privately at our Baker Street clinic, with results typically available in around two to three weeks.

Hair loss is one of the most common reasons people request the test. Some mineral imbalances may be associated with thinning, brittleness, poor hair quality, or slow growth. But hair loss has many possible causes - including iron deficiency, thyroid disorders, hormonal imbalance, stress, genetics, and broader nutritional gaps. Because of that, hair mineral analysis is best combined with other investigations such as ferritin, thyroid, and vitamin D testing rather than used alone.

This matters, so it's worth being straight about. Hair mineral analysis is widely used within nutritional, functional, and environmental medicine and in wellness screening. At the same time, some scientific bodies have questioned its use as a standalone diagnostic tool. The reasonable position - and the one we take - is that it's a supportive investigation, best interpreted alongside your medical history, symptoms, blood tests, and clinical assessment.

People commonly consider testing when dealing with unexplained fatigue, low energy, brain fog, hair changes, or general nutritional and wellness concerns, as well as those interested in fertility (for which targeted testing is also available), environmental exposure, or preventative health. It tends to appeal to anyone wanting a longer-term view of their mineral status rather than a single snapshot.
