Are you going/have you gone grey, or are you just growing tinsel for the festive season?

I started "growing tinsel" when I was 21. Far more salt than pepper now, but still have all of it at 55. In contrast to my son, who shaves what little hair he has left - takes after his maternal grandfather who was completely bald before I met him.

The balding gene does come from the Mother's side of the family. 
About 1/2 of my Mother's brother have hair and all of my Dad's side does so we will have to see what my 2 son's end up with. 

"The genetics of hair loss are not straightforward; it’s not just about inheriting a “bald gene” from your mother or father. Instead, multiple genes contribute to the likelihood of experiencing hair loss. These genes can come from both maternal and paternal sides, debunking the myth that baldness is inherited solely from the mother’s side.

Hair loss is often an inherited trait passed down on either or both sides of the family.

Well, my hair is not as thick as it was back in the day, but it still covers my scalp. :)

Which side of the family does a thin head come from?

Same genes. No one just wakes up and they are bald. 

Dol you even read what you write?  You said your husband has a thin HEAD.  How does his HEAD GET THIN?

The hair on his head is thinning.....

Maybe he's not a fathead.

LOL ...

Much of it from dealing with a certain person from SOCAL, I'm sure.

It helped. :)
