I have re-evaluated the cause of my hypertrichosis. I am inclined to think it was topical bethametasone which I used experimentally to see if it will help to cover bald patches on the beard. I can tell it was absorbed systematically , because I felt an acute effect every time I was applying it. Although it didn't help with the beard, but probably caused excessive hair growth in other parts of the body. Not sure what to do about it, but i found some info that most corticosteroids are IL-17a blockers are associated with hypertrichosis.Progesterone should be the most effective way, and eating less protein to lower prolactine and increase SHBG. You could also directly apply some progesterone on the areas where the hair annoys you most.
