Sometimes referred to as: alopecia, androgenetic alopecia, alopecia areata, scarring alopecia, effluviums, male pattern hair loss, female pattern hair loss
The causes of hair loss can be broken into roughly six categories: effluviums (hair loss due to emotional of physiological stress), alopecia areata (an autoimmune process), scarring alopecias (an inflammatory condition of the scalp), infectious causes, physical causes (e.g. too much tension placed on hair), and genetic causes (male and female pattern hair loss).
In any year, about 35 million men and 21 million women are experiencing hair loss.
85% of men by age 50, and 45% of women by age 80.
Mostly psychological, but can lead to increased sun-related skin cancers on the scalp.
The most common type of hair loss is androgenetic alopecia, also known as male-or-female pattern baldness. It is genetically predetermined, and is the result of hormones—called androgens—acting on hair follicles and progressively shortening their life cycle.
In men, androgenetic alopecia is recognized as a progressively receding hairline and the loss of hair at the crown. It typically affects half of men over 50 years old, but can start as early as adolescence. In women, it is characterized by a more generalized thinning on the top of the head that only rarely leads to complete baldness. These cases can also begin early, though they more commonly presents after menopause.
Telogen effluvium, the second most common type of hair loss, affects people who undergo some type of significant physical, metabolic, or emotional stress. Many women, for example, experience this after giving birth. Hair abruptly shift from the anagen (growth) into the telogen (resting) phase and falls out. Surgery, severe injury, chronic illness, or rapid weight loss due to diet can also trigger telogen effluvium.
