Where ever I go, I see men checking out blonde women. Like today in the gym, there were three other women in the weight room. All young, all fit. All slim. Yet all the guys couldn't keep their eyes off the blonde, even though the brunette was squatting with 60 kilos which looked like more than her own bodyweight.
Through history too, men seem to like their blondes. 'Blondes have more fun,' all that. So what is it about them?

Blondes are genetic rarities, especially in most non-Scandinavian countries in the world (i. e., most of them), so they're going to stand out as being unique and highly noticeable under any circumstances.
Beyond that, there is all of the "marketing" that has made the "California Blonde" into the "ideal woman" in the Western world (and to some degree worldwide). Blondes in ads provably sell more beer and burgers than brunettes, and as long as that's true, they'll keep casting blondes for their TV ads.7

It's interesting how some unique or rare features are stereotypically considered beautiful, like blonde on a woman but other unique or rare features are stereotypically considered weird or unattractive like red hair on men. Makes me wonder sometimes. I think historically, blonde has been associated with femininity, delicacy, daintiness, sexually appealing, etc for whatever reason, and it's been perpetuated today because it sells and woos mates for historical and modern associations.
Maybe initially came about because 1) blonde is very commonly seen in children, and so it is associated with youth, innocence, purity 2) blonde people tend to be light skinned, so for the same reason most world cultures prefer light skin (upper class, not out in the sun like lower class, etc) 3) loved iconic famous blondes maybe popularized it.0
