My hair color keeps changing as I get older

So, I was a total blonde until I hit four.
Then from age four to ten, I went brunette.
Between ten and nineteen, my hair turned pitch black, kind of like someone from Turkey.
Fast forward to now—I'm twenty, and suddenly it’s back to brown, and it just keeps getting lighter and lighter...

Is this normal? Am I losing my mind or something? Is there some weird disorder going on here?

Bigfoot said:Don't sweat it, it's totally fine. My daughter was born with this super dark, almost black hair, then when she was little it turned honey-colored, and now it's just brown.

Eh, okay, good.

I was getting a bit spooked 🙂
