Hey fellas, has anyone noticed a change in their facial hair since surgery?

I've had several friends ask if I dyed my goatee, and I have to admit that it seems to have a hell of a lot less gray than three weeks ago...

Anyone else see any changes? Thickness, ability to grow, etc.?

Decided to give a try at growing a beard. I'm 9 days out and it seems very patchy. It does look a little thicker than in the past. My face isn't nearly as round as it used to be and I have a more prominent jaw line than in the past. I don't think there is more hair, just less real estate to cover. I'll give it a month and see if it looks like there's potential. My doctor has me on some B Vitamins which I hope helps. I'm even experimenting with Minoxidil.
