Androgenetic Alopecia

Androgenetic alopecia, also known as male/female pattern baldness, is a common form of hair loss in both men and women.

Causes

The exact cause of androgenetic alopecia is not fully understood, but it is believed to be related to:

• Hormonal imbalance: An excess of dihydrotestosterone (DHT), a potent form of testosterone, is thought to contribute to the condition.
• Genetics: Family history plays a significant role in the development of androgenetic alopecia.
• Aging: Hair growth slows down with age, and the hair follicles produce thinner, shorter hairs.

Symptoms

The symptoms of androgenetic alopecia vary between men and women:

• Men:
  • Thinning hair on the scalp, particularly on the crown and temples
  • Receding hairline
  • Bald spots or patches
• Women:
  • Thinning hair on the scalp, particularly on the top and crown
  • Widening of the central parting
  • Diffuse hair loss throughout the scalp

Diagnosis

Androgenetic alopecia is typically diagnosed based on:

• Medical history: A thorough review of the patient's medical and family history.
• Physical examination: A visual examination of the scalp and hair loss pattern.
• Hair pull test: A test to assess the amount of hair loss.
• Blood tests: To rule out other underlying conditions that may be contributing to hair loss.

Treatment

Treatment options for androgenetic alopecia include:

• Medications:
  • Minoxidil (Rogaine): A topical solution applied directly to the scalp to stimulate hair growth.
  • Finasteride (Propecia): An oral medication that slows down hair loss and promotes hair growth.
• Hair transplantation: A surgical procedure that involves transplanting healthy hair follicles from one part of the scalp to another.
• Laser therapy: Low-level laser therapy (LLLT) or photobiomodulation (PBM) to stimulate hair growth.
• Wigs and hairpieces: For those who prefer a non-medical solution.

Prognosis

The prognosis for androgenetic alopecia varies depending on the individual and the effectiveness of treatment. With proper treatment, it is possible to slow down or stop hair loss, and in some cases, promote new hair growth.
