Why not? In the Tom Riddle flashback, Dumbledore's hair was still 
auburn, and we know he was 100 at that time (because JKR told us in 
chat that he is 150 'now' and the flashback was 50 years ago). JKR 
told us in chat that McGonagall is 'a spritely 70' and her hair is 
still black (unless she dyes it...) While Hooch has gray hair: SS 
says: "Their teacher, Madam Hooch, arrived. She had short, gray hair, 
and yellow eyes like a hawk."

I like for McGonagall and Hooch to be the same age, so either Hooch 
grayed younger or McGonagall IS dying her hair. I like for McGonagall 
to have been born in 1926 like Tom Riddle and therefore been one of 
Tom and Hagrid's classmates. However, Hooch was born in 1926 and the 
Silver Arrow was no longer made after 1926, it would have been an old 
used broom when she learned on it.
