I had white blonde hair as a child, now it’s still very light as an adult. I occasionally highlight it, but it’s still blonde without dye.
No one in my family has blonde hair ! I honestly thought I was adopted as a child.
My mum had very dark hair (now grey), my dad the same, almost jet black in wedding photos of them. My brother has very dark brown hair. My maternal grandmother had naturally jet black hair, my maternal grandfather had dark hair, my paternal grandmother had auburn hair and my paternal grandfather had dark brown hair too!
How does this work?!
My son takes after me with white blonde hair though.
