I think the women hair gives you a glimpse into her personality.
For instance when her hair looks so groomed that every hair looks perfectly sitting in place, I see that girl as overly annoying.
But when lets say 10%ish of her hair looks imperfect, but the rest looks pretty nice, then she is perfect. (HEH!)
However, during sex, her hair should look a lot messier than the 10% suggested above.
Women look better when it looks like their hair has been manipulated.

I dislike when the hair is trimmed in a horizontal line or when it covers her forehead.
Hair looks better when it's trimmed in a somewhat disorganized fashion,
I don't know how hair dressers call that technique.
It kinda looks like they are butchering your hair when they are trimming it, but when they are done, your hair looks more voluminous and awesome.
Overly tight Pony tails and curl hair I usually dislike and it is a strong enough dislike to skip a scene.
I interpret long hair as a sign of very high libido. So those girls appear as "super sexy" to me.
Regardless of body type, long hair increases their attractiveness IMO.
What I mean by "long hair" is that, when she is standing up, her hair reaches all the way down to her lower back.
And when she is arching her back and pushing her butt, her hair touches her ass slightly.
I guess it's just easier to show you, what "great hair" looks like to me:

As far as hair color goes, as long as the hair texture and everything else looks pretty to me. I'll like it no matter what.
That's just my opinion though
