Frequently Asked Questions

Bioresonance is a complementary wellness approach that was developed in Germany in the 1970s. It's based on the idea that foods and everyday items have their own energetic frequencies. In our lab, your hair sample is compared against the frequencies of hundreds of items, and your report shows which produced a high, moderate or no response. Bioresonance isn't recognised by mainstream medicine and hasn't been validated by clinical research.

"Food sensitivity" is a general term for feeling unwell after eating certain foods, often because your body finds them harder to digest. People commonly describe bloating, gas, tummy discomfort, headaches or tiredness, usually a few hours after eating. These symptoms can have many causes, so talk to your doctor if they keep coming back.

A food allergy is a reaction by your immune system. It usually happens quickly, can be triggered by a tiny amount of food, and can be serious. Symptoms can include hives, swelling, wheezing or vomiting. Allergies are diagnosed by a doctor or allergist using blood, skin prick or patch tests. If you have trouble breathing or swelling of the face or throat, call 999.

No. Our tests don't test for allergies and can't tell you whether you're allergic to anything. Allergy tests measure immune responses, such as IgE antibodies in the blood, and a hair sample can't do that. If you think you have an allergy, please see your doctor or an allergist.

Some people notice symptoms around non-food items, such as household cleaning products, fabrics, pollen or pet hair. Our report includes a range of these everyday environmental items as well as foods. It doesn't test for environmental allergies such as hay fever or dust mite allergy, which need testing by a doctor.

An elimination diet means removing a food you think may be causing symptoms for about four weeks, then reintroducing it to see whether the symptoms return. It's the approach most doctors and dietitians use to identify food intolerances. Take out one food at a time, keep a food and symptom diary, and talk to your doctor or a registered dietitian first, especially before cutting out a whole food group.

You can keep eating your usual balanced diet, apart from the food you're testing. Make sure you replace any nutrients you're removing, for example calcium if you cut out dairy. Always keep avoiding any food you know you're allergic to, whatever your report says. A registered dietitian can help you plan meals.

We offer three tests. The Basic test covers 400 items, the Advanced test 900 and the Ultimate test 1,350. The items include everyday foods and drinks and non-food items such as household products.

No, we don't send out a kit. Once you've ordered, you can send your sample straight away, which saves time and packaging. Place your hair in a small sealable bag with your name and redemption code, and post it to: Simply Sensitivity Checks, PO Box 1644, Northampton, NN1 9LQ with the correct postage.

About 5-10 strands, each at least 2.5cm long. You don't need to cut a large amount, and a small snip from underneath your hair works well.

Yes. Hair pulled out from the root is fine, as are cut strands.

Yes, as long as you're the only person who uses the brush. Hair from a shared brush could mix your sample with someone else's.

Yes. If you can't provide hair from your head, body hair such as arm, leg or chest hair is fine. Please don't send pubic hair.

Yes. Dyed, bleached or chemically treated hair can still be sent.

No. We don't test during pregnancy or while breastfeeding. If you have symptoms during this time, please speak to your doctor or midwife before changing your diet.

Yes. We don't test children under 6. For children 6 and over, a parent or guardian must place the order and send the sample. Please talk to your child's pediatrician before making any changes to their diet.

Put your hair in a small sealable bag. Include a note with your full name and your redemption code, then post it to: Simply Sensitivity Checks, PO Box 1644, Northampton, NN1 9LQ. You'll need to pay for postage yourself, so check you've used the correct stamps for the size and weight.

We'll email you as soon as your sample arrives at our lab. If you haven't heard from us within 10 days of posting it, please contact us.

You'll usually receive your results within 3–5 working days of our "sample received" email.

We'll email your report to the address you used when you ordered. You can also view and download it from your account. If it hasn't arrived, check your spam or junk folder first.

Use your report as a starting point for your own wellness journey, not as a diagnosis. If an item showed a high response, you could try removing it for about four weeks as part of an elimination diet, then reintroducing it and noting any changes. Take out one item at a time and keep a food and symptom diary. Never reintroduce or eat a food you already know you're allergic to, whatever your report says, and talk to your doctor or a registered dietitian before making big changes to your diet or if your symptoms continue.

Yes. If you bought your test directly from us, you're covered by our 100% money-back guarantee. If you bought through Groupon or another retailer, please contact them for a refund, as we can't process refunds for third-party purchases.
