  • UNCOVER DIETARY & ENVIRONMENTAL ITEMS THAT MAY BE CAUSING SYMPTOMS. When your body reacts to certain foods, daily surroundings, or struggles to utilize key nutrients, it may cause digestion problems, skin breakouts, and fatigue. Testing helps you avoid guessing and identifies exactly which foods and environmental factors need temporary elimination, reduction, or rotation.
  • FOOD INTOLERANCE, ENVIRONMENTAL SENSITIVITY & NUTRITION TEST COVERING 1052 ITEMS. This health assessment reviews your bodys response to 658 foods, 282 household materials and outdoor items to help identify which exposures may be contributing to symptoms like diarrhea, gas, acne, and headaches. It also uncovers how your body may be absorbing and utilizing 112 essential vitamins and minerals, giving you insight into where nutritional support may be needed to support nutritional balance, steady energy, and mental clarity.
  • HOW IT WORKS: 3 EASY STEPS. Testing can be done completely at home. 1) Register your hair analysis test by following the included instructions. 2) Collect 10 to 15 strands of hair. 3) Mail your sample to our lab using the included prepaid shipping materials. Once the lab receives your sample, results are available in about 4 days.
  • MAKE DIET & LIFESTYLE CHANGES BACKED BY DATA. Each food intolerance and environmental sensitivity item is organized into four response levels, helping you understand what to remove temporarily, rotate in moderation, and keep in your routine. Your nutrient imbalance report highlights vitamins and minerals your body may not be utilizing efficiently, guiding food adjustments and supplement decisions to support improvements in digestion, energy, skin, hair, and nail health.
  • 3RD-PARTY VERIFIED & HOLISTIC PHYSICIAN APPROVED. 5Strands is the only intolerance, sensitivity, and imbalance test of its kind backed by independent third-party study data. Each sample is reviewed in a certified U.S. laboratory and goes through a double-pass analysis process to ensure consistent and reliable results. More than 345,000 people and pets have used our hair analysis test to pinpoint their food triggers, environmental stressors, and nutrient absorption gaps affecting their daily health and comfort.

  • Hair analysis
Since all period, that I was dealing with Lab, I had only one issue with was solved very quick and easy for me. All people, who were involved, were kind, friendly and sympathetic! I want to thank you for such a great work, affordable prices and full information. This test gives precise information of your body functions, deficits and allergy. Which is quite difficult to get from the blood test, because not everything can be measured by the blood analysis. ... show more

  • Life Saving!
This company is awesome! The process is simple, easy and quick. They send you the test box. Inside is an instruction sheet and “Get to Know You” questionnaire. 5Strands asks you to provide hair strands, then put them in the provided sealable ziploc bag. Lastly, you are given an envelope to send your results back in through USPS. That’s it! Not invasive at all like allergy testing can be! I had my results in a week and it was very easy to understand how to read my results! 5Strands had made it clear what they can help you with. I think where most customers misinterpret their data is thinking that these intolerance symptoms are comparable to allergy symptoms. That is not correct and 5Strands makes sure to state that multiple times! This test is meant to give you awareness of your body chemistry and how it reacts to environmental and food properties that you come in contact with. Although you may see Salmon on your Level 3 results (most severe) and “feel nothing” when you are eating salmon... it could still be causing unseen symptoms, like bloating or gas that you may not notice! Others also notice the same food in multiple categories.. well foods can be consumed in different forms (raw & cooked). I have noticed that raw onions make me way more gassy than cooked onions and it showed up right in my results!! On day one I have already cut out a couple foods that I would normally eat and I have had a dramatic increase in energy and comfort! I can’t thank this company enough!! Way to go, 5Strands! ... show more

The only problem I had with this was I couldn’t get my own hair at the root myself so I asked my hairdresser to do it.

  • "Severe Deficiency" Results Disproven by Follow-up Blood Serum Test - Stay Away!
First, I get that a hair test is different from a blood test. However, when results are so wildly disparate one has to conclude that either the test is flawed, or that they substituted their pet dog's hair for mine, or maybe that they are simply playing results roulette or using a dartboard to determine the value of a given test. I take very good care of myself, eat really healthfully (well, usually ;-) ), and also take a variety of supplements to make sure that my body has everything it needs - and I really stay on top of this stuff! So I was eager to see what adjustments I could make, based on my test results, to further fine tune my regimen. And I pored over my results as soon as I got them. I should have known that something was rotten in 5Strands the moment I saw that they don't even proofread their results - right there in one of the headings on the results pages it read: Standatd Environmental ..instead of Standard Environmental. Could a place that was so sloppy with how their reports get sent out be any better in terms of what they were actually reporting? I chose to overlook it for the time being, and looked at the actual results. Now, the very first thing you will see in your results is the section called 'Nutrition'. This is where they report the results of their tests for your levels of various vitamins, minerals, and amino acids, traces of which will be present in your hair, such as Vitamin K, Vitamin D, Selenium, and Glycine. Have I mentioned that I take a variety of supplements, and generally take good care of myself? One of the supplements is a powder which provides 100% of the RDA for every single vitamin, mineral, and a lot of other things (yes, really). On top of that, I take a separate Vitamin D supplement, for bone and health reasons. In fact, I often get more than 10,000 IU of Vitamin D a day (don't try this at home unless your doc approves it). And as a serious vegetarian, I also get an abundance of Vitamin K (clotting factor). In fact when I had surgery for which I had to take an anti-coagulant, they had to factor that into my dosage - Vitamin K is found in leafy greens, of which I eat a lot :-). Oh, and I also take a separate Glycine supplement. So, as I said, I take good care of myself, and my vitamin and mineral levels should all be really good. So I was *shocked* when the first thing that I saw in my 5Strands test results was a moderate *deficiency* in Vitamin K. And I was *stunned* that it said that I had a *severe* deficiency in Vitamin D. It also claimed that I had a 'moderate' Glycine deficiency. Surely I couldn't be deficient in all of these things that I am actually supplementing, and on the high dosage end at that? So last night I got the results of my *blood serum* test that my physician did, including for Vitamin D. The results? Quoting from my blood test, for Vitamin D: 95.1 ng/mL What's normal, you ask? Again, quoting from my blood test: 30.0-100.0 ng/mL As you can see, I am not only not deficient in Vitamin D (let alone "severely deficient"), but I am at the high end of 'normal' (nobody has ever called me normal before, let alone at the high end of it! ;-) ) This alone calls into question the rest of the 5Strands results. But the fact that they also reported me as deficient in K and Glycine, when the odds are so very slim that I am, means, to me, that basically all of their results are questionable, at best. By the way, I asked 5Strands what "Standatd" meant (for all I knew it was some sort of acronym or such rather than a typo), and their response was to tell me all about the various tests that they sell - a different response (yep, I was responded to by two different people) gave me the excuse that they were going through some website changes "that have required us to manipulate our reports a little bit." This caused me to write back to them saying "I'm sorry, how can I trust the reliability of your test results when you don't even have the quality control to check the results you send out for basic typographical errors?" Here was their response, verbatim (copied and pasted from their email): "Im am sorry that you feel that way. Many of our systems are automated and we do not review every single report that is sent out to our customers. It would be impossible to review each set of results due to the volume of reports that are processed. All we can do is apologize for the typographical error that was made when the lab processed the results." Really?? "Im am sorry"?? At that point I gave up. The moral of this story is: don't bother purchasing this home test - have your doctor do a hair test (or blood test, depending on what you are testing for) and send it to a reputable lab. ... show more

  • Excellent experience
I initially bought two tests that I thought were different, but a customer service rep reached out to me to let me know that were very similar and asked if I would like a refund for one of them or to substitute the test for something else that covered things not included on my initial order. I found this to be so honest and refreshing. I was very grateful to hear from them on the front end and I substituted a test. My test results were fast and easy to decipher. Having the app is a really nice bonus as well. Would recommend this company to others! ... show more

  • Unfortunately, this testing isn't supported by much real scientific evidence.
The process of receiving the kit and mailing back hairs was simple enough (though I used arm pit hairs, so a bit of plucking...). Mailed the kit back and got a PDF in my email within about a week. Results had a lot of surprises on it, including my entire morning routine of coffee, almond milk and brown sugar. While I was prepared to make major changes to my diet, I couldn't help think that I first needed to look up how credible hair-based testing actually was for these kinds of sensitivities. I brought out our good friend Chat GPT to explain everything currently known about hair-based testing for sensitivities and this sums up what it said in great detail: "Based on the current scientific understanding and consensus, hair-based sensitivity testing for food allergies or sensitivities is not considered a credible or reliable method for diagnosis. The composition of hair primarily reflects the presence of minerals, substances from hair care products, and environmental contaminants. It does not provide a direct measurement of immune responses or specific food sensitivities." It went on to explain in great detail that the human hair contains nothing whatsoever related to the immune system itself, so that extracting results for sensitivities is impossible. So now I'm kind of left with a test I don't find credible, but I am planning to lay off of coffee and sugar for a while. Which, regardless of this test, will have known benefits. ... show more

  • This test is amazing and accurate!
I have been having many health issues since my colon surgery in 2017. So very confused about various foods suddenly that did not seem to agree with me. My grandson told me about this test hair strand test that he had heard about and I ordered it immediately. My issue is that I don't necessarily break out in a rash so I don't know about various products for certain but this test confirmed my questions about products and foods that I was eating. For instance, the test revealed that I should avoid certain apples and it is so true. Red delicious apples are one item that I did have an allergic reaction too earlier that I could confirm that the test was accurate. They give me a burning tongue and burning lips right after I bite into them and the pain lasts for awhile. There were other items on the list that seemed to correlate with what I had been questioning. One was a surprise as I discovered that my body is very high in arsenic. Figured out that it is the rice products that I have been consuming for many years. Rice can be good for you but one has to be careful about the source because of the arsenic in the soil that can get absorbed into the rice. I looked at my shelf and it was full of rice products. I hope this helps and encourages others who are facing unexplained health issues. I will now start eating other items that I know are o.k. and then after six weeks, re-introduce one thing at a time if I so desire. ... show more
