I think the LW is perfectly fine in thinking the way her dad's doing it doesn't suit him (a faculty member at my uni has died a single spot on the very top of her head bright blue; it looks exceedingly odd), but there's nothing wrong with anyone dying their hair fun colors at any age! And it's his hair. He can do whatever the hell he wants with it that brings him joy.
