Androgenetic alopecia

Androgenetic alopecia (also known as pattern hair loss or balding) is a common form of hair loss in both men and women. The condition is characterized by a progressive thinning of the hair, primarily on the scalp, due to the effects of androgenic hormones on the hair follicles.

Causes

The primary cause of androgenetic alopecia is a genetic predisposition, which is inherited from either or both parents. The condition is linked to the presence of certain androgen hormones, particularly dihydrotestosterone (DHT). DHT binds to receptors in the hair follicles, causing them to shrink and eventually stop producing hair.

Symptoms

The symptoms of androgenetic alopecia vary between men and women. In men, the condition typically begins with a receding hairline and progresses to thinning on the crown of the head. In women, the hair loss is usually more diffuse, with thinning occurring over the entire scalp.

Diagnosis

Diagnosis of androgenetic alopecia is typically based on the pattern of hair loss and a patient's medical history. In some cases, a biopsy may be performed to rule out other causes of hair loss.

Treatment

Treatment options for androgenetic alopecia include topical treatments such as minoxidil, oral medications like finasteride, and surgical procedures such as hair transplantation. However, the effectiveness of these treatments varies from person to person, and they may not be able to fully restore lost hair.
