Can tests be run on people with little or no hair?
Hair can be collected from several head locations and combined to obtain the required amount of hair. If the head hair is too short, body hair can be used as a substitute. If body hair is used the timeframe represented by the test is approximately one year due to the different growth pattern in hair below the neck. NOTE: DO NOT mix head and body hair.
