ALOPECIA ANDROGENÉTICA: REVISÃO DA LITERATURA

Abstract

Androgenetic alopecia (AGA) refers to a chronic and hereditary dermatological condition characterized by the progressive miniaturization of hair follicles, affecting men and women in different patterns. Its etiology is multifactorial, involving genetic predisposition and hormonal influence, mainly due to the action of dihydrotestosterone (DHT) on genetically sensitive hair follicles. It is estimated that the condition affects around 80% of men and up to 30% of women. The clinical presentation tends to worsen with factors such as stress, poor nutrition, and metabolic disorders, which accelerate hair thinning. Treatment, which remains non- curative, is based on pharmacological approaches such as minoxidil and finasteride, as well as emerging therapies involving stem cells, botulinum toxin, and hormonal antagonists. Combined therapeutic approaches have shown greater efficacy in stabilizing the condition and partially restoring hair density. Consequently, AGA has gained prominence both in scientific research and clinical practice, requiring a multidisciplinary approach that promotes the physical and emotional well-being of patients.
