Blondes do have a striking appearance, and they do tend to get noticed. I also think some men view them as the ultimate conquest. I don't really take that view - there is more to a woman than hair colour.
I can only speak from personal experience here, and I among my past girlfriends there were a number of natural blondes. Out of those, there were one or two whose pubic hair wasn't very thick. Others had pubic hair as thick as most brunettes I had experience of. One of my earliest blonde girlfriends had a beautiful little bush, a light brown, sandy colour, certainly thick enough to hide her labia quite well and with a real forest around her anus, yet her legs were very naturally smooth and free of hair. No way did she need to shave any area from thigh to ankle. She was a beautiful little thing, and I still think fondly of her. There was another whose pubic hair was so pale and lacking contrast with her skin colour that it was almost invisible. My point is that there seems to be variation, at least in my experience, and I wouldn't like to generalise.
I've been intimate with more brunettes overall, most likely because there are many more of them. There seems to be plenty of variation in pubic hair thickness with them also. Just as with natural blondes, brunette pubic hair can be thick ir sparse. My wife is a dark brunette, and her pubic hair is thick overall, maybe just slightly thinner around her anus than everywhere else. From the front I can often still see her inner labia, as they are quite long. If she is shaven, they can look quite large.
During my twenties I had two girlfriends of Indian descent. One had pubic hair much like my wife, and the other was fully shaven. It would have been interesting to see others for comparison, but other girls got in the way first. LOL
