Not sure what constitutes good hair and what doesn't but what I do know is that I like women who keep their hair together. Doesn't always have to be done. But she has to be able to take care of it. That's a sign of good hygiene to me.
if its coarse and pricks my fingers when I run my hand through it then it ain't good
if its soft and I can run my hand through it without being injured then its good
