Can you make hair follicles grow where it never has grow before ?

We have hair all over our bodies. (Except, for instance, on our palms and the soles of our feet). It's just finer, or shorter, or thinner, than on the top of our heads, etc. If we knew how to stimulate follicles that are no longer producing (like men who go bald), we'd ALL know about it. In short, if you have a hair follicle, it has grown hair. What you ask doesn't happen.
