Amount of Hair Required

Our lab requires a tablespoon of your hair for testing. Other labs may require less hair, but Doctor’s Data tests for 19 toxins and 22 nutrients, and other labs may not test as thoroughly. If your results seem a bit unusual, or if the lab feels that they may have made an error, they re-run the test a second time to secure accuracy (at no extra charge). You can’t beat this form of quality!

We are always disappointed when a patient doesn’t send us enough hair, but this serves as a reminder that Doctor’s Data is one the finest labs performing the hair analysis because they will not compromise your results with too little hair in your sample.

Add Dr. Hull’s talents for interpreting your hair analysis to the quality of our lab, and you have a tool for wellness that is top-notch.

You can submit a tablespoon of head hair or a tablespoon of pubic hair. You do NOT have to pluck your pubic hair, but merely cut it as close to your skin as possible.

When submitting a head sample, if you have short hair, you can simply get a hair cut and have your barber place the clippings in a zip-baggie. If your hair is long, try to submit a tablespoon of hair off the shaft as close to your scalp as possible, preferably at the back of the neck.
