I had kept mine clean shaven for the better part of six years. Last October I wanted to see if I could grow it out still. About a quarter of my hair didn't grow back. I went bald while I was bald. 

Grass doesn't grow on a busy street.

You guys made me laugh. 1 1/2 on the top and 1 on sides for eight years now. Two things I miss the most.  Non-prescription sunglasses and the ability to wear a visor. I wish Charlie Ingram would read this thread. Good Lord man, accept the concept of bald is beautiful. There is a significant demographic of chrome domes based on the number of us who read the thread.

FYI, RECEDING is when your hairline is moving away. ReSEEDing is what you do AFTER that starts to happpen.
