Does no hair equal no personality?

I shaved my head last week, as I always do in warmer weather. You would not believe how this affects people's attitude toward you! Work colleagues shake their heads knowingly, or stop talking to you. People in the street seem to get nervous when I'm walking in the same direction as they are, some give sympathetic glances like they assume I'm on chemotherapy or something. Some chickens even cross the road! My mother tut-tuts at me, and friends pretend not to notice and snicker behind my back. And no, I'm not paranoid - not everyone behaves in this way - but I jusy find peoples preconceptions irritating. A woman I know who did the same said main were threatened by her bald head and became more aggressive. Any ideas as to why this is?

Hello Phil:

I certainly don't have an answer for you but it reminded me a of few things to share with you.
There was one place where I worked for a short while and this programer supervisor had bald hair. He would purposely shave it and to his co-workers they felt they needed to tell me that so and so is someone that loves doing diffirent things in life and he is fun. He was very funny and enjoy life.
I think that sometimes people do desire to be a certain way and they are not brave enough to act on it. Sometimes people fear asking someone a question feeling that it will be stupid to make any comment etc that can come across as personal.
The second story that this reminds me of is the time I work again for another company and this guy normally has black hair and during the weekend he wanted to die his hair beach blonde but failed to realize that he should have bleach his hair and it turned out burnt orange.
Anyways he entered a room full of co-workers and noone made a comment. He asked everyone" don't you see something diffirent about me?" and someone said that they notice that he is not wearing his earring. I said" ya you have orange hair" and then everyone started to giggle and some admit that they noticed but was scared etc.
