Male pattern baldness follows a classic pattern that is best illustrated by using the Norwood Classification System, which ranges from type 1 (minimal frontotemporal recession) to type 7 (loss of all but a small rim of hair). [4] Types 2-6 categorize the typical progression of hair loss.

The clinical presentation in women differs somewhat from that of men. In women, hair loss along the hairline is typically spared, with thinning throughout the top and upper sides of the head is more diffuse in women than in men.

In one suggested scenario, preoperative screening consists of a health-history questionnaire that includes questions about easy bruising, anesthesia problems, allergies, mitral valve prolapse or other conditions necessitating preoperative antibiotics, and all current medications (including herbal remedies). Study results have confirmed the superiority of good history taking and physical examination compared with any blood screening test for determining a patient's medical suitability for surgery.


Physical Examination

Upon initial patient evaluation, the physician must first determine the etiology of the patient’s hair loss. Only after first ruling out (1) systemic causes such as thyroid abnormalities, polycystic ovarian syndrome, or iron-deficiency anemia; (2) dermatologic causes that may be treated medically; (3) and telogen effluvium (temporary hair loss that resolves over a few months’ time), should a surgical approach to hair loss be considered.
