Hair

I like a nice haircut. Short, long, medium, blond, brunette, red, black, green whatever is fine. I even enjoy a humorous haircut the mullet, the bowl cut, etc... but hair is unique in that it is dead and yet still needs to be loved and taken care of. I see people out there with hair that is just well dead looking. Why? I feel like we only have hair in modern times to attract others or to make ourselves more attractive in general. If you are not using your hair for this purpose why do you have it. Many people look fine without it. And if you have it and are not taking care of it why not? Simply washing your hair is not enough. You must blow dry or style or add product or color or cut do something! But to my eye there are those who allow the hair to grow. Washing and letting it air dry ends splitting laying flat to the head. I understand some people for religious reasons do not cut their hair but let it grow. I understand this but usually see people of these cultures take great care of their hair, or hiding it away. So I guess I don't understand why people choose to have hair if they don't "use" it for anything?
