Lipoma removal and minoxidil/finasteride used for male pattern baldness.

Hello, I have a lipoma on my forehead I would like to get removed, as of now it is relatively small. I was wondering if the removal of this lipoma would (likely) have consequences on the effectiveness of minoxidil and finasteride used for male pattern baldness. I only ask because my surgeon said that sometimes patients will get a numb feeling on the top of their head after such a procedure. I didn't think of this question to ask while I had a chance talking to him.
