Female "androgenetic" alopecia

Do all women have a family history?

Female androgenetic alopecia also known as female pattern hair loss. Some people refer to it as the female equivalent of male balding.

Androgen hormones and genetics have a very clear role in men. For women, it is not as clear. Not all women improve their female pattern hair loss with antiandrogen medications - and not all have a clear genetics.

Between 15 to 30 % of women with female pattern hair loss do not have a strong family history of balding.

We still have a ways to go in understanding the role of hormones and genetics in female hair thinning.
