Foods eliminated

I have eliminated the foods that you recommended and have been thrilled to add back some foods that I previously thought were problems for me.

I feel so much better! I have recommended your testing to many people. Thank you!

Happy mum

My mother has been having some stomach issues and wanted to find out exactly what was wrong, the doctors couldn’t tell her.

Now my mom can make those subtle food changes and have a much happier stomach and not be questioning everything she eats!

Frequently Asked Questions

What is a sensitivity?

Sensitivities include all those reactions to food and non-food items that can activate a non-immune mediated response.

Instead they can be caused by not having the right enzymes you need to digest certain foods or a reaction to food additives or preservatives.

Find out more about food sensitivities.

How do I take a hair sample?

The safest way to take a hair sample is to ask someone else to help you. Using your forefinger and thumb, gather 3 or 4 strands and slightly twist the hair together.

This will make cutting the hair sample much more accessible and keep all the hair strand in the same direction.

Try to cut the hair sample as close to the scalp as possible, using one cut. If you do not have anyone to help you, using a mirror may help ensure you avoid injury.

Find out more about how to take your hair sample.

Will I receive anything in the post?

My hair is very short, or I am bald. Can I still complete the tests?

My hair is dyed, permed or treated; will this affect the result?

Can I complete a hair test on a child?

Children can complete a hair sensitivity test once they reach five years old due to their immune system changes and the importance of eating a varied diet.

Infants have not yet built up their tolerance levels to items, highlighting false positives in their test results.

However, it is up to the parents or guardians if they would still like to proceed knowing this.

Is there anything additional to pay?

If you’ve purchased one of the sensitivity tests, you will have to pay the postage cost back to the processing centre, which then sends the sample to the UK.

We try to keep our costs as low as possible (by not sending out physical hair testing kits) so that we can offer such a comprehensive test at the price offered.

Please ensure the correct postage amount has been paid as we are not liable for any extra charges.
