Causes

Here is a list of medicine that might cause a woman to start developing abnormal facial and body hair:

Steroids

Certain birth controls

Danazol

Cyclosporine

Minoxidil

Spironolacton (though I have not seen an increase in hair and I am currently on it)

Nicotine (smoking may cause you to sprout hairs)

 

These are the ones I have heard of or researched on. Feel free to add to the list!
