Is Ross Lynch a natural blonde?

Answer 1

It does not look like it. You can usually tell if someone's blond or if that's their hair color by their eye brows. His eye brows are brown, not blond. So the way it looks, he is not a real blond. Don't trust tumblr by the way. It usually fake stuff and people joking around.

Answer 2
