I always had very thick hair and wore it long - long enough to be able to sit on it. I got a small bald patch in my late twenties but the worse thing was going thin on top. It made my hair look straggly especially as it was still really thick on the back and sides. I had it cut shorter which wasn't quite so bad for a while but as it got thinner on top and the bald patch got bigger I started to look like Coco the Clown. A couple of years ago I decided I'd had enough and shaved it all off and now I keep my head totally shaved.
I also had a full beard for many years but I shaved it off about ten years ago when it went grey. I've recently grown it back and have a very grey goatee. I'm nearly 50 but I look very young for my age - most people guess my age to be in the mid 30's - so having a white beard really throws them. I've had people ask me why I dye my beard white.
A couple of weeks ago I shaved the beard off but it made me look even younger so I'm growing it back.
It's funny because on the one hand I really miss having long hair - it was almost a trade mark for years - but I also like being completely bald. It's the bit in between that I couldn't stand - going bald is a lot worse than being bald.
