What are intolerances?

A food or environmental intolerance is when your body finds it harder to deal with certain foods or everyday items. Unlike an allergy, an intolerance doesn't involve an immune response, and symptoms often build up gradually, which can make the cause hard to pin down.

  • Food intolerances can happen when the body struggles to digest or break down certain foods, for example because of low levels of specific digestive enzymes.
  • Environmental intolerances relate to things in your surroundings, such as dust, pollen, pet dander or household products.
  • Commonly reported symptoms include bloating, tiredness, skin flare-ups, joint discomfort and headaches, although these can have many possible causes.
  • Many people find that reducing their exposure to certain items, guided by a structured elimination plan, helps them feel more comfortable day to day.

Simply Sensitivity Checks uses bioresonance, a complementary wellness approach, to give you personalised insights into items you may want to explore. It doesn't diagnose allergies or medical conditions, so if you have ongoing symptoms, always speak to your GP.

Frequently asked questions

Why do you use hair instead of blood or saliva?

Hair is quick and painless to collect at home. There are no needles, no appointments and no special storage, and you only need a few strands.

What do I need to send?

4–5 strands of hair if it’s longer than 2.5cm, or 8–10 strands if it’s shorter, cut as close to the root as you can. Put them in a small sealable bag with your name and reference number, and mail them to our lab.

How long will my results take?

You’ll usually receive your results by email within 3–5 working days of your sample arriving at our lab. We’ll email you when it arrives, so you’ll know when to expect them.

Where can I find my results?

Your report is emailed to you as a PDF, so you can save it, print it or share it with your doctor or dietitian. If it hasn’t arrived, check your spam folder or contact us.

Will this test diagnose an allergy or intolerance?

No. Our tests are complementary wellness products, and they don’t diagnose allergies, intolerances or any medical condition. If you think you have an allergy, or you have ongoing symptoms, please speak to your doctor.

Who can take the test?

Adults, and children aged 6 and over with a parent or guardian’s consent. We don’t test children under 6, or anyone who’s pregnant or breastfeeding.

How long do you keep my hair sample?

We keep your sample for 7 days after testing in case it needs to be re-checked, then securely dispose of it. We never use it for anything else.
