Do not order from this company - they took over a month to notify me of "receiving" my specimen and I have yet to receive my results. Yet they sent me dozens of emails saying "congrats on receiving your results this is day 3, 4, 5, etc. of elimation" I emailed them a half a dozen times and called at all business hours +left detailed messages and STILL have yet to hear back from a single person, yet when you call they say their hours are "24/7"
After doing some research, and I encourage you all to do the same, try looking up SCHOLARLY articles regarding testing allergies and intolerances via hair sample. There is NO CLINICAL EVIDENCE OF ACCURACY. It's all placebo effect people. Our immune system and gut microbiome are far too complex to be able to test any clinically significant factor on a piece of hair. Such a scam.
*also my friend who took the test bought this test and got her results and then was gifted another blood test shortly after and was given VASTLY different results on each.
Don't waste your money people.
