L64: Androgenic alopecia

Androgenic alopecia, also known as male or female pattern baldness, is a common type of hair loss that affects both men and women, although it's more prevalent in men. It results from a combination of genetics and the hormone androgen. Typically, the condition shows as a receding hairline and hair thinning on the crown in men, and a general thinning of hair density in women without a receding hairline. Progression of androgenic alopecia varies greatly among individuals but is generally slow and progressive. It often begins in the late teenage years or early adulthood and continues to develop over many years. Androgenic alopecia primarily affects the scalp, resulting in hair loss, but does not lead to any other physical ailments or complications.
