Also known as Androgenic Alopecia or Alopecia Androgenica
This is a common form of hair loss in both female and male humans. In males in particular, this condition is also commonly known as male pattern baldness.
Hair is lost in a well-defined pattern, beginning above both temples. Hair also thins at the crown of the head. Often a rim of hair around the sides and rear of the head is left, or the condition may progress to complete baldness.
The pattern of hair loss in women differs from male pattern baldness. In women, the hair becomes thinner all over the head, and the hairline does not recede. Androgenic alopecia in women rarely leads to total baldness.
