I really can empathize. I had brain surgery and both where they took out the tumor and where they put in a drain (sorry if TMI) I don't have hair and my hair is thin to start.

Your situation, I'm sorry to say, actually sounds worse because it's in the part. Can you part it on the other side? Or do a style without a part?

I hope it turns out that the surgery is minimal. Please post back! BTW, I have found that coloring my hair makes it thicker, so if that is an option for you, think about it. The permanent color coats the strands.

Good luck!!!
