First of all, I have blonde hair. I thought it would be necessary to mention that.
I like my blonde hair, because I feel it's a staple of who I am. However, in the context of potential romantic partners, I have a strong preference for brunettes. Having blonde hair isn't unattractive, it's just that it pales in comparison to brown hair (quite literally). The contrast between brown hair and a girl's skin really catches my eye, and having noticed that, blonde hair in comparison makes people's faces look washed out to me.
However, I am in the minority on this one. It's practically universally accepted that the majority of men prefer blonde hair, albeit a slight majority. In my experience, no matter how much the sample changes, it's always been about 60/40 in favor of blondes. Which leads me to your next question...
"Does someone being blonde work in their favor or not in society?" - For females, it indirectly does. Having blonde hair makes a girl more attractive to a majority of guys, and it's a well-known fact that attractive people have an advantage in quite literally every aspect of society. It's not necessarily the same for guys, however. In fact, it may very well put them at a disadvantage, because as it seems, the majority of women prefer dark hair in men. Apparently it's considered more "masculine"--as if a hair color can be inherently "masculine" or feminine", but I digress. And it's not just a slight majority as is the case with men, but rather a vast majority. In addition to being on average less appealing to the opposite gender, it seems that people of both genders attribute delinquency to men with blonde hair. I speak from personal experience. However, there is an uncontrolled factor in my case, because being presumed a slacker may have more to do with the length of my hair than the color of it, so take it as you will.
As for natural vs dyed hair, men don't care as long as they can't tell the difference. Obviously, it isn't attractive if it's obvious that it's fake. However, if you did a good job dying it, they aren't gonna care. That goes for just about everything, not just hair color.1

Overall, I find light hair aesthetically pleasing. In terms of what I find sexually attractive in the opposite sex, blonde hair is better than dark hair UNLESS that dark hair is combined with light (blue/green) eyes.
Men with dark and green eyes are, like, the epitome of human genetics, in my opinion.1
