You might not believe me but this seems to be slowly working for me. Stimulate the bald spot with lite finger rubs. Try to catch, push and play with any fine hair that is there. Do it for a month or two.

I found out this worked for me by accident. After developing a large bald spot on the front of my head I began a habit of playing with it. Mined you it was smooth like a babies butt. No hair follicles. So, it felt weird. After a month of lite rubbing and lite scratching I began to notice something prickly. Peach fuzz.

I didn't think anything of it because I lost hope already. Still, I had the habit to play with it. It grew more. I took notice and learned playing with stimulates it. I know this works because I've done it to my other bald spots.
