What color was Al Capone's hair?

Answer 1

Here's what his grandaughter had to say. "I remember the twinkle in his eyes. He had blue eyes. Most people don't know that, that he had blue eyes."

Also his neice Deirdre Marie Capone said the same in her book "Uncle Al Capone"

Answer 2

Al Capone had black hair, and as he aged, the hair on top of his head became thinner, while the rest of his hair remained thick.
