I’m just referring to average prices. I do know that asking for extreme things usually costs more for women, to this I won’t argue. If I went into a salon asking for the same thing, I would get the same price (my hair used to be 3 feet long, which I grew out to donate to Locks of Love). It’s the length that does it, and what you ask them to do, that determines the price.
I did say that Barber Shops (catered to men) tend to be cheaper, but it’s because they don’t exactly have the training to do higher-end things. I doubt they could even layer hair. 
But yeah, $10 is pretty much standard for anything as long as it’s shoulder-length or less, or otherwise any length as long as they don’t have to use scissors. If you expect something fancy, you need to be prepared to pay for it, especially if you’re going to a Barber Shop, because they tend to play guesswork with scissors (as said, they just aren’t trained for it most of the time). $20-35 is standard for women at salons/stylists, but it’s usually standard for a scissor cut even in a Barber Shop if your hair is longer than shoulder length (this is due to labor, cleaning, and skill regardless of customer gender). I just moved here two months ago, but locally, the most recent hair cut I had (longer than shoulder-length) cost me $10, but to be fair, the guy works alone, in a small town, and determines his own prices. It’s $15 for a standard scissor cut from him, and he’ll charge more if it’s long enough to do so.
I usually go to a Barber Shop, not because they cater to men, but because it’s where my grandmother took me. Her hair was down to her knees (she was 5’3, so that’s saying something). She’s also why I grew my hair out for 5 years to donate, because she died of cancer… It was a strain emotionally to go to a different one recently after going to the same one for nearly 10 years (mostly out of preserving her memory, in a way). Otherwise, yeah, I’d go to a salon. The atmosphere in a Barber Shop is nice, but I’ve only met two Barber Shop barbers that would ask how my day was, or what I did that day, and it would actually sound genuine (like they actually cared)… Something that feels more genuine in Salons, regardless of the gender of the person cutting your hair. It’s kinda… Boring when they don’t wanna talk, or make it sound like they feel forced to do so, ya know?
Anyway, it’s not a sexist thing in that case. Trust me, I’d be flying off the rails if it was (I’m an egalitarian). It’s literally due to skill of the person cutting your hair, and what you ask them to do. Typically a barber will still charge you less than a stylist, but a stylist is specialized, as well. Also, Salons around here are $15 usually, regardless of gender, although they do discount for children most of the time. Barber Shops don’t. Barber Shops charge you $10 as long as they get to use clippers, while salons charge $15 even if they do. This is again mostly because of their training that was required, what you ask them to do, the length of your hair, et cetera…
