William Katt's hair in "Carrie"

Matched his bush

I say perm.

Exhibit A

His hair isn't curly in his most recent pics, so unless he spends time straightening his hair now, he had a perm in "Carrie".

Got to meet him and he was very cute. It's my favorite movie and I have met the entire cast, from Spacek, Travolta to Edie McClurg. It's like a sports fan getting to meet his whole favorite team.

Wasn’t it pretty much the same in GAH? If not that’s a long time to be hanging on to a style Robert Reed only flirted with.

Hey, R2. When I was young I had very curly hair. When I started going gray, my hair lost its curl.

His father, 40s star Bill Williams, had beautiful, wavy blond hair.

I'd say: natural.

Here's his dad in a sailor suit.

I always thought he was handsome with sex appeal. I liked his character in “Carrie.” He was adorable and charming.

Did Carrie plan to pop her cherry with him on prom night?

Natural. In the '70s, guys grew their hair out and didn't style/straighten it to make it look "acceptable." Katt was also a surf bum in those days, and the salt air made any natural curliness even moreso.

You can see at R2 that even when it was short, his hair still was a bit curly in the '80s. If it's straight now it doesn't mean he got perms back then, because everybody's hair changes by the time they're in their seventies.
