The man Henry was talking to had greying hair and looked to be about fifty.
Her greying brown hair was tied in a loose bun.
His face, under the greying hair, had gone still.
He was a big man, with thick straight greying hair brushed back neatly.
The general idly scratched his greying hair as he read the letter.
Her greying red hair was tied back with a green bandana.
This small, uninteresting woman with short greying hair and a plain face?
Kit sat back in his chair and ran one hand through his greying hair.
His long greying hair was parted in the middle.
One could almost hear the friendly smile and the greying hair in the voice.
