Do the intolerances have to be in my body to detect them on the results?

No, it is not necessary to have all the items in your body, nor do you need to consume them prior to testing (that would be quite labor intensive)!

Your hair carries your unique signature which responds in the same way as the rest of your body does.

Therefore, when your sample is tested, our technology will provide feedback as to how well your unique signature responds to the unique signature of the items we test for you.
