Female pattern baldness is triggered by Androgens (male hormones). It may occur at anytime from puberty but is most commonly seen after the menopause. It’s the most common type of hair loss seen in women.
All women have a small amount of male hormone and these levels can become more pronounced if levels of female hormones decrease as occurs during menopause.
In men and women the male hormone testosterone is converted to Dihydrotestosterone (DHT) by the enzyme 5-alpha reductase thus causing susceptible hairs to fall or thin out.
It is thought that hair loss in women don’t proceed as far as it does in men because they only have half the amount of 5-alpha reductase.
Women also have increased amounts of the enzyme Aromatase, which converts male hormones into female hormones preventing additional female hair loss.
