Alopecia androgenetica

Alopecia androgenetica, also known as male-pattern baldness or female-pattern baldness, is a common form of hair loss that affects both men and women. It is characterized by a gradual and progressive thinning of the hair on the scalp, which usually begins at the crown and temple regions in men, and in the central scalp in women.

Alopecia androgenetica is caused by genetic and hormonal factors, with the hormone dihydrotestosterone (DHT) playing a key role. DHT is a derivative of testosterone, and it binds to hair follicles, causing them to shrink and produce thinner and shorter hair over time. Eventually, the hair follicles become so small that they can no longer produce visible hair, leading to baldness.

Treatment options for alopecia androgenetica include topical or oral medications, such as minoxidil and finasteride, which can help to slow down or even reverse hair loss in some people. Hair transplant surgery is also an option for those with advanced hair loss. However, it's important to note that not all treatments work for everyone, and results may vary.
