When did he lose his hair?
I just bought a DVD set of his performance in "North and South" from 1975 and he had a full gorgeous head of hair. However I couldn't help but wonder if it was a wig because I've never seen him with his own hair before. I've always seen him wearing wigs.
However this performance has confused me because the hair looks like it really belongs to him.
Does anyone know when he began balding? As he was bald 12 years later in Star Trek TNG's pilot.
