On a related note, why does blond hair get darker and browner with age, when I was very young, say up until about 10 or so, my hair was naturally a very distinctive platinum blond. When I see most other kids this age with blond hair, it is typically the same color. However, my hair has been steadily “browning” with age. I’m in my early 20s now and my hair is dirty blond / light brown now. Most people I see my age and older that are “blond” (naturally, not dyed) really have this dark, sandy blond hair color. Why is this?
For many people with blond hair (myself included), the amount of time they spend in the sun affects the color - the more time outside, the lighter the color. Adults tend to spend all day working whereas kids have recess, PE and summers and afternoons off.
I don’t know if there’s more to it than that.
That’s why I think there is a sexual attraction element to blond hair. Blond signifies youth, youth = healthier and fertile which makes lots more hunters and gatherers.
I got mine from my mom’s side of the family.
If you’re talking about GEICO-type cavemen, i.e. Neanderthals, at least some of them were redheads.
Also, despite their extremely dark skin, many Australian Aborigines have blond hair, which is thought to be a result of sexual selection, perhaps combined with a “founder effect”.

That is a legitimate question. I was blonde as a toddler and my hair got darker and darker to the point where I have to argue with people now whether I have black hair or really, dark brown hair. My youngest daughter is trending the same way.
People can be flip all they want but I think the OP has a really good question and I am pretty sure that no one in the world has the answer yet. The same thing applies to skin color although lots of people think they know the answer based on simplistic information.
