Alopecia

Androgenetic alopecia or common baldness is hair loss that is deemed physiological in men from a certain age and is rarer in women. This type of alopecia is the most common cause of hair loss, affecting 80% of men by 90 years of age, 35% of women of childbearing age and 50% of menopausal women. It is polygenic in nature meaning that various genes are inherited and occurs due to the action of androgens in genetically predisposed individuals.

It manifests as the progressive loss of hair on the head in the frontotemporal (front and side) and occipital (rear) areas, which is replaced by thinner finer hair, eventually leaving areas of baldness without hair.
