What is the Origin of Androgenic Alopecia?

The name is derived from the key causative agents and the clinical outcome: 'Androgenic' refers to androgens, the class of steroid hormones involved, while 'alopecia' is a Latin term originating from the Greek alōpekía, meaning "fox mange" or baldness. This etymology highlights the historical recognition of hair loss as a distinct medical entity. It is a dermatological condition intrinsically linked to the endocrine system.

What is the Mechanism of Androgenic Alopecia?

The pathogenesis involves the conversion of circulating testosterone into the more potent androgen, Dihydrotestosterone (DHT), within the hair follicle's dermal papilla cells, a reaction catalyzed by the enzyme 5-alpha reductase. Genetically susceptible hair follicles possess increased androgen receptors and heightened sensitivity to DHT. DHT binding initiates a process of follicular miniaturization, shortening the anagen (growth) phase and progressively shrinking the follicle until it produces only vellus, or fine, nearly invisible hairs.

Androgenic Alopecia

Meaning

A common, progressive form of hair loss characterized by a distinctive pattern of follicular miniaturization on the scalp, primarily driven by androgenic hormones. This condition is also widely known as male-pattern or female-pattern hair loss, reflecting its sex-specific prevalence and presentation. The clinical manifestation involves a gradual thinning of hair density and caliber over time.
