Worth a try. Very impressed.
Was sceptical but results came back showing all I had suspected. All from a hair sample, not blood test required. Couldn't get the GP to test for gluten at all. Have recommended you to several friends.
Thank you.

Very inaccurate
Very inaccurate, said I had a 100% thyroid imbalance which led me to get an actual blood test which came back perfect. While I was there I told the nurse and they could not believe that a hair test could find half of the things it said it did

Hi Declan,
Thank you for sharing your experience with us. We’re sorry to hear that the results you received didn’t align with your medical testing and that this caused concern. We understand how important it is to feel confident in any health-related information you receive.
Our hair testing is based on bioresonance technology, which is designed to provide wellness insights rather than medical diagnoses. It's important to clarify that our test is not a replacement for clinical blood work or professional medical evaluations. While some customers find our service helpful in identifying areas to explore further, we respect and understand that it may not meet everyone's expectations or align with conventional testing.
We truly appreciate your feedback and will continue to work on improving transparency and clarity around what our test offers.
Warm regards,
Customer Service Team,
Test Your Intolerance.

The whole thing is a scam
The whole thing is a scam
I went to the doctors with my test results and he laughed me out of the clinic.
Hair does not show intolerances
Everything this company said I was intolerant to so happened to be the main food items I’d eaten the past month.
From the mouth of my GP “it’s a complete scam”

Hi Victoria,
Thank you for taking the time to share your experience — we genuinely appreciate all feedback, even when it's critical.
We're truly sorry to hear that your experience left you feeling disappointed and that your GP did not support the validity of the test. Our testing uses bioresonance technology, which is a non-invasive wellness approach used by many around the world. That said, we fully understand and respect that medical professionals may hold differing views, especially when comparing it to traditional diagnostic methods.
Our intention is never to replace medical advice but to offer additional insights that some individuals find useful as part of their broader wellness journey. We’re sorry to hear this wasn’t the case for you, and we recognise how frustrating that must have been.
