Find out how a simple hair-based intolerance test can uncover food-related triggers behind your digestive issues. Learn how to prepare your sample for accurate results with Check My Intolerance.
Digestive problems can be frustrating, painful, and hard to pinpoint. Whether you’re dealing with bloating after meals, unpredictable bowel habits, or long-term IBS symptoms, food intolerance may play a significant role in how you feel. At Check My Intolerance, we provide a simple hair-based at-home intolerance test to help you identify foods that may be contributing to your gut discomfort.
No blood. No clinics. No confusing appointments. Just clear answers from the comfort of your own home.
In this guide, we’ll walk you through everything you need to know before taking your test and how to make sure your results reflect your body’s unique needs, especially if you’re trying to get to the root of long-standing digestive symptoms.
Many people with digestive issues have tried all sorts of solutions – from cutting out gluten to taking probiotics or even going on restrictive diets. But without clear information about how your body reacts to certain foods, you could be guessing in the dark.
Some common symptoms of food intolerance include:
These symptoms don’t always appear immediately after eating, which makes it challenging to establish a connection. That’s where a hair-based intolerance test can help.
By analysing a small sample of your hair using bioresonance technology, we can identify potential food intolerances that may be contributing to digestive distress. It’s a non-invasive, effective way to gain insight into your body and start making meaningful changes.
To ensure your results are accurate and reflective of your current intolerances, it’s essential to follow a few simple guidelines when preparing your sample.
Try to avoid colouring, bleaching, or chemically treating your hair for at least 3–5 days before cutting your sample. Hair that’s been recently treated may contain chemical residues that could interfere with the bioresonance reading.
Don’t worry if your hair is dyed, our lab can still work with it, but untreated hair provides the most precise results.
We recommend washing your hair the night before collecting your sample using a gentle, fragrance-free shampoo. Avoid using heavy conditioners, oils, styling products, or dry shampoo afterwards.
Only send in dehydrated hair. Damp hair can become mouldy or damaged in transit, which may affect the quality of the analysis.
The best place to collect your hair sample is from the nape of the neck or behind the ear. These areas are less likely to have been exposed to excessive styling or sun damage.
Use clean scissors to cut a small amount (around 4–5 strands, at least 3cm in length), then place it in the labelled bag included with your test kit.
One of the most common questions we’re asked is whether you need to reintroduce foods you’ve cut out before taking the test.
The answer is no. Hair testing reflects longer-term exposure, and we assess how your body is currently responding to various food substances, even if you haven’t eaten them recently. There’s no need to upset your stomach or reintroduce foods that cause discomfort just for the sake of the test.
Once your sample arrives at our UK-based lab, it is analysed using advanced bioresonance technology. This non-invasive technique evaluates how your hair frequencies respond to hundreds of typical food and environmental substances.
Within days, you’ll receive a comprehensive report highlighting:
We understand how exhausting it can be to deal with digestive problems day in, day out, especially when it’s unclear what’s causing them. That’s why our test is designed not just to provide results but to help you take practical steps toward feeling better.
Once you’ve identified your key intolerances, you can begin making targeted changes to your diet, reducing or eliminating certain foods for a set period and monitoring how your gut responds.
Many of our customers report significant improvements in:
By focusing on what’s relevant to your body, you avoid unnecessary food restrictions and make informed decisions that support your long-term health.
Unlike blood-based IgG testing, which reflects short-term immune responses and can be affected by recent dietary changes, hair testing gives a longer-term view of your body’s reaction patterns.
This makes it especially useful for individuals with ongoing digestive symptoms who have already adjusted their diet and want a clearer understanding of what might still be triggering discomfort.
Plus, it’s:
If you’ve been living with unexplained bloating, IBS, or digestive discomfort, our at-home hair intolerance test offers a safe, accurate, and accessible way to start finding answers.
No guesswork. No hassle. Just clear insights you can trust.
