Androgenetic alopecia, commonly known as male or female pattern baldness, is the most prevalent form of hair loss. It affects both men and women, though it presents differently.
Cause: Androgenetic alopecia is hereditary and influenced by sex hormones. In men, it’s linked to the hormone dihydrotestosterone (DHT), a byproduct of testosterone. DHT shrinks hair follicles over time, leading to progressively thinner and shorter hair growth until follicles miniaturize completely. In women, hormonal fluctuations throughout life, such as during pregnancy or menopause, can play a role.
Symptoms:
Men: Receding hairline at the temples, progressing to a “M” shape. Hair loss thins the crown of the head.
Women: Thinning hair, particularly noticeable at the part line, with a general decrease in overall hair volume.
Treatment:
Minoxidil (Rogaine): Topical medication that stimulates hair growth.
Finasteride (Propecia): Prescription medication that blocks DHT production (for men only).
Low-level laser therapy: Promotes hair growth through light stimulation (efficacy is debated).
Hair transplantation: Surgical procedure that moves hair follicles from a donor area to the balding scalp.
