Androgenetic Alopecia

Definition: Androgenetic Alopecia (AGA), also commonly known as male pattern baldness or female pattern hair loss, is a genetic predisposition to hair thinning that affects both men and women. It’s the most common cause of hair loss, affecting up to 50% of men by age 50 and a significant portion of women after menopause.

Cause: Androgenetic alopecia is caused by a combination of genetics and the hormone dihydrotestosterone (DHT). DHT shrinks hair follicles over time, leading to shorter and finer hair growth until eventually, follicles miniaturize completely, stopping hair growth altogether.

History: Androgenetic alopecia is a condition known for centuries. Early descriptions of hair loss patterns can be found in ancient texts, with the understanding of the underlying cause evolving over time. The role of hormones in AGA wasn’t fully established until the 20th century.

Treatment: There’s no permanent cure for Androgenetic Alopecia, but several treatments can slow down hair loss and promote regrowth in some cases. These include:
– Minoxidil (a topical medication that stimulates hair growth)
– Finasteride (a medication that blocks the conversion of testosterone to DHT)
– Low-Level Laser Therapy (LLLT)
– Hair transplantation (a surgical procedure to move hair follicles from a donor area to a bald scalp)
