Why did Billy Zane go bald?

[FishFrancis]

He had a full head of hair in 1997 in Titanic...But then 2001 rolls around (Zoolander) and...bald. What the fuzz?

 

[ocularnervosa]

He was either wearing a toupee or shaved his head. Actors do that.

 

[RabidAggression]

He must have been wearing a wig because he was bald in Tales From The Crypt: Demon Knight and that was two years before Titanic.

doesn't take long for someone to start having hair problems. who knows, the bald look probably suited him better
