You and I may think that, but for many people apparently it's more bewildering than interesting. An unusual hair colour conjures up all sorts of weird stereotypes about the person concerned.
If they don't instantly suspect you're a druggie, a prostitute or a nutcase, they'll decide you're a wild unreliable party girl, or your boss will say you look too unprofessional for a public-facing role.
There are still plenty of prejudices around hair. Ginger hair can attract snarky remarks. Afro hair styles are frowned on by many employers. Grey hair can make a woman "too old for the job".
Length itself is still an issue. Women are expected to have long hair, men short hair. Even schoolboys have been excluded from school for having over-long hair. I had long hair once in my John Lennon phase, but I've had short hair ever since - a lot more manageable.
And of course there's baldness. Perfectly okay for men (though a lot of men hate being bald and would rather not be). But not okay for women. If you have cancer, then baldness is acceptable. Otherwise it's shocking and ugly and surely you should be wearing a wig.
It's extraordinary that a simple thing like human hair should be subject to such a complicated tangle of prejudice and disapproval and false assumptions. But then the whole human body is subject to just that. Accepting it for what it is seems to be a non-starter.
I guess the only people who can get away with any old hairstyle are celebrities like rock musicians, hospital patients and prisoners. Anyone else had better tread carefully.
PS: A wonderful quote I just came across: "Humans have a big cluster of dead keratin tendrils growing from our heads and we arrange them in different configurations and worry about whether other people find our keratin tendril arrangements aesthetically pleasing."
