4.4.2.5 Head Hair Standard

Pull at least 25 head hairs and place them in the pre-labeled ‘Head Hair Standard’ envelope.

Pull the hairs, by hand, from a variety of areas near the patient’s scalp, including the root of the hair, such as the front, middle, back and both sides. Include grey hair.

Be sure to collect various lengths and colors.

Hairs must be pulled by hand, not with scissors or tweezers. Tweezers damage the hair and the root is needed.

If head hairs adhere to the examiner’s gloves, place the entire glove in the pre-labeled ‘Head Hair Standard’ envelope.
