I have this "long blond hair" clichè that really irk me a little. Mostly because when I was a child, my grandma always enphatised it when reading me fairy tails, or always expressing how good looking are blonde hair, and many of the older Disney princesses always had blond hair, and I am dark haired, tomboysh, with never hair longher than chin lenght. so I felt excluded a little.
(stupid thing, I know)
I guess I'm feeling a little repulsive of the clichè because "the long haired blond girl" clicè was almost everywhere. From Super Mario, Disney's princess, and so on.
Long-haired blonde, here! I think it's maybe worth mentioning that these clichés upset me as a blonde as well. Growing up, I was really confused by the characterization of damsels in distress in various media, though at that time couldn't put my finger on why. Generalization of anything based on something as arbitrary as hair colour is kinda silly. And shouldn't overshadow how we assess an individual's character, in my opinion.
On topic: Solas would totally agree. ("JUST BECAUSE I DON'T HAVE HAIR DOESN'T MEAN I DON'T HAVE A SOUL". Oh wait, that's supposed to be red heads. But maybe he's technically one of those, too.)
I know what you mean. I love Samus (Metroid) but the fact she's a blonde just puts me off her so much. ;_;
Also, have a heart since I'm out of likes. 
Is it solely the fact that Samus has blonde hair that puts you off? I have blonde hair, and I would casually like to state that I am pretty great, though still probably only about 1/6th as badass as Samus.
At any rate, I am flipping my hair so hard right now.
I legit don't care what color or length a Lavellan's hair is. As someone with hair down to my elbows, I actually find long hair is FAR easier to style, keep out of my face, and all around deal with than short hair ever was. Serious business time? French braid it. Katniss is doing it right.
