Why we test hair

Unlike hair, blood tests can be affected by your last meal, stress or other factors. Hair can store information for periods up to 3 months, or more, allowing us to get a greater picture of your body’s health.

A few reasons why analysing hair is better:

  • Blood samples start to deteriorate quickly.
  • Hair testing is a much faster process resulting in quicker results to our customers.
  • Hair testing is non Invasive, so there is no need for any painful prick tests.
  • Because our testing process is completed quickly and efficiently, we can pass these cost savings onto our customers.

Frequently asked questions

How do I take a hair sample?

The safest way to take a hair sample is to ask someone else to help you. First, brush your hair upwards to reveal the root area at the back of the head, then holding a small amount of hair between the finger and thumb, cut the hair as close to the scalp as possible. If you do not have anyone to help you, try using a mirror, which may help ensure you avoid injury.

My hair is very short, can you still complete the tests?

The hair sample does not have to be from the head; we can test hair from any part of the body including leg, arm or chest.

Where are the tests processed?

All tests are processed at our testing facility in the UK. Once the hair sample has been received at our testing facility you will receive your results within 7 – 14 working days.

How long will it take to get my results?

7-14 working days from the date that we receive your hair sample and test submission form. Please allow for postage time also.
