Daddy Ron hair?

When Alex was born my mother examined his crown and wondered if he might just have hair like my father - Daddy Ron hair. My dad has this notorious lock of hair that will not lay down without a lot of encouragement.

Alex woke up like this a few weeks ago.
It was the first time I had to use a brush on the boy.

And we just wondered - is it Daddy Ron hair?

If I can get ahold of one, I will post a comparison photo.
