Wellness testing
What it is
A non-invasive test that checks a few strands of your hair against a wide panel of food, drink and everyday items.

4.9/5 from 30 reviews left on our site.
The number of items covered is impressive and the results came back quickly. A couple of sensitivities surprised me, so I’m working through a proper elimination now to see how I respond. It’s been useful for direction rather than quick fixes.
I wanted the full picture rather than testing a small list of foods, and I’ve dealt with bloating and brain fog for a long time and felt like I was just guessing. The emailed report was detailed (I had to read it twice to take…
I already eat quite clean, so the additives and environmental section was the biggest eye opener for me. Results were easy to access and arrived faster than expected. It hasn’t solved everything overnight, but I feel more confident about what to adjust.
I train quite a lot but was struggling with low energy and random stomach issues. The test covered everything in one go rather than doing multiple smaller tests. A few sensitivities came up that I honestly hadn’t considered. I’ve adjusted my diet slightly and feel…
I’d tried eliminating dairy and gluten before with mixed results. My results highlighted some additives I hadn’t even thought about. Not everything matched what I assumed, but it’s helped me approach changes more logically instead of guessing. Overall happy with it.
I decided to test after months of feeling sluggish and not really knowing why. The testing process was simple and results came back quicker than I expected. The report is detailed, maybe a bit overwhelming at first, but once broken down it’s quite clear. I’m…
I’d been struggling with stubborn weight gain and low mood for over a year. The Test revealed sensitivities to gluten, cashews, and even some fruits I ate daily. Removing them has transformed how I feel—lighter, brighter, and finally in control of my health.
I tested after constant sinus issues and congestion. Shocked to see high sensitivities to dairy and wheat... I removed both and noticed improvement in under a week. Breathing clearer and sleeping better.
The test was incredibly easy to do—sent off a hair sample and got results in days. I found out I was reacting to several foods I thought were “healthy.” Made the swaps and now feel way less bloated and tired.
I took the Ultimate Test to figure out why I was always feeling foggy and sluggish. The results were eye-opening—citrus, dairy, and soy. I cut them all out and it’s made such a difference. Worth every penny!
Really clear instructions and quick results. I’d been suffering with itchy skin for months—turns out I had sensitivities to almonds and oats. Who knew? My skin has calmed right down since eliminating them.
I’ve tried everything for my gut health and nothing worked—until this. The test flagged high sensitivity to eggs, garlic, and peppers. I changed my diet and my stomach issues disappeared. Honestly, this saved me years of trial and error.
Most common questions
Do you send a test kit?
No. It’s a digital service: everything you need arrives by email, so you can post your sample the same day you order.
How much hair do you need?
4–5 strands, cut close to the scalp. Coloured or treated hair is fine.
What’s the difference between an allergy and an intolerance?
Allergies involve the immune system and can be serious, so they’re diagnosed medically. Intolerances and sensitivities tend to cause slower, milder symptoms such as bloating or tiredness. This test is a starting point for exploring those, not an allergy test.
How long do results take?
Within 3–5 working days of your sample arriving at our lab, or within 48 working hours if you add priority results.
Can children take the test?
Yes, from age 6. Under-18s need a parent or guardian to order for them.
Does hair dye affect results?
No. Coloured, dyed and treated hair are all fine.
What do I do with my results?
Use your elimination guide: remove the high-response items for 6–8 weeks, then reintroduce them one at a time while tracking how you feel.
What if I’m not happy?
You’re covered by our 30-day money-back guarantee. Email us within 30 days of your order and we’ll refund you in full.
