How to take a hair sample
- We need a minimum of a ½ teaspoon of hair to obtain accurate results.
- Please take your hair sample from the back of your head.
- Cut your hair as close to the scalp as possible and supply us with the sample that is closest to your scalp.
- Place the sample in a small paper envelope (not plastic).
- If you have dyed hair and are doing an Optimum Nutrition test you will need to supply us with a sample from other parts of your body (please see FAQ for more information).
- If you have dyed hair and you are doing 2 or more tests including an Optimum Nutrition Test you will need to supply us with 2 samples (one head hair and one from another part of the body) clearly labelled.
- If you do not dye your hair we only need one sample of head hair for your tests.
- If you do not have head hair please provide hair from another part of the body.
- If you are unable to provide a hair sample we can also use a set of unpolished nail clippings. Alternatively, you can provide a buccal swab taken using a clean cotton bud swiped on the inside of both cheeks and placed in a paper envelope.
