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 (without drawing blood). If you do not have anyone to help you, using a mirror may help ensure you avoid injury.
