Am a brunette naturally but I've dyed my hair bleach blonde before, and the difference in treatment is huge. As a blonde I was told by men all the time that they "find brunettes more attractive" as if I care what they think of me based on my hair colour, or anything for that matter? I've had my blonde martial arts teacher call my mistakes a "blonde moment" in class, and call her own small absent minded mistakes the same. And she's a female martial arts instructor, you'd think maybe she wouldn't perpetrate negative stereotypes about women. Blonde was seen so negatively and even though my hair was clearly dyed, the whole blonde archetype was forced onto me anyway! I think only gingers have it worse when it comes to hair based judgement, and in my country gingers are quite common. When I got sick of dealing with roots every few weeks, I said fuck it and dyed my hair back to my natural shade. It's makes me way more inconspicuous and I think it's made people assume I'm smarter, as if my intelligence is determined by a bottle of hair dye. But that's just my two cents.
