The test includes one intolerance test, one nutritional deficiency test, and one metal test. Your intolerance test results include all items that have shown a score of 85% and higher. After completing thousands of tests, we now know that 85% is the turning point where symptoms begin to develop into an allergy/intolerance.

Once you have your hair sample and completed test form, please ship it to the address on your test form.
From our Canadian hub, the samples are shipped to our UK testing facility twice a week. Once the samples have been safely delivered to the testing team, you will be updated by email. We then aim to get your results to you (via email) within 72 hours of your sample(s) arriving with the team.

To increase your quality of life you should, over a period of 4–6 weeks, completely exclude the items your body is intolerant to. During this time your body will get the peace and quiet it needs in order to repair itself. After this period you can either take a new test to be sure your body is “ready” or, gradually and in small increments reintroduce the items to see if there is any reaction. As for the nutrients you may be missing, we recommend that you follow our dietary guidelines and make sure that your body gets the nutrients it needs to stay healthy and strong.

In addition to being less invasive and significantly cheaper, your last meal may affect the results of a blood sample, whereas a hair sample has the information stored for a longer period and reflects a wider time frame.

The safest way to take a hair sample is by asking someone to help you. First, brush your hair upwards to get easy access to the hair roots and the back of your head. Hold a small amount of hair between your finger and thumb, and cut the hair as close to the scalp as possible (without pulling any blood). If you do not have someone who can help you, please use a mirror to avoid accidentally hurting yourself.

When your order is completed, instructions will be sent to your email along with your receipt (i.e. we will not send test kits). Simply take 4–5 hair strands from your scalp place in a small plastic bag then put in an envelope along with a completed form (instructions are emailed post order).

No, we test the composition of the hair sample, so the hair dye will not affect your test results.

Only a small amount; 5 individual strands. We don’t require clumps of hair.

There is quite a big difference between being allergic, intolerant, or hypersensitive to a substance however, the symptoms often resemble each other. For those who get ill from their diet, it may feel equally bad. The devil is known by many names, some might say. Our test results will shed a light on what intolerances you might have, in other words, which ingredients to avoid. An intolerance may pass after a period of time, while an allergy lasts for life.

Unfortunately, we don’t recommend the test for anyone below the age of 6. Younger children have not yet built up their tolerance levels, and this can give false results in the lab.

Yes. Pets can suffer from similar intolerances to humans. We offer a Pet Intolerance Test for cats and dogs with 60 checks for common pet food brands, in addition to environmental factors.

Tests can be easily ordered on our website. Should you have further questions, please don’t hesitate to email us.

Your order number will be clearly stated on your order confirmation email that you will have received when you made the initial purchase.
