More specifically, are 2’+ (no, I’m not stupid; I really do mean 2 FOOT PLUS) long hairs left in the sink gross? Is it gross to find said hairs stuck to the walls, in giant clumps stuck to your socks, and, worst of all, occasionally coming all the way through your digestive system? Is it not reasonable for me to tell my roommate that if he’s going to wear his hair that way, he should be responsible for making sure it doesn’t interfere with other people in the apartment? His argument is that if it’s as little work as I say, (it’s not the work. It’s the fact that it’s HIS hair and it’s pissing ME off.) and I’m the one who has a problem, it’s therefore MY problem, not his, and I should just clean it up. After all, he washes the one water glass or so a week I put in the sink along with his stack of dirty dishes. And he washed my coffeepot once. He claims that if he sees it, he cleans it up. Oh, great. That should be a GIVEN. Is it reasonable for me to ask him to, say, take a quick look at the sink after he brushes his hair? He doesn’t seem to think so. Validation, please!
Eh, maybe this should’ve been MPSIMS. Or the Pit if I get much more irate. Move as you see fit, moderators.

For some mysterious reason, as soon as my own 2’ hair leaves my head I think it’s gross. So, I’m always sure to clean it up right away so no one else has to deal with it and its ickiness. It’s his hair, the roommate should clean it up. No question. Especially from anywhere in the bathroom – sink, tub, drains, shower curtain.
I agree with delphica. I have long hair, too, and if you’re going to make the choice to wear your hair long, you have to clean up after yourself.
Perhaps you could encourage your roommate to comb his hair more often. This removes loose hair and decreases random shedding.
Actually, his hair-brushing is the problem, as it seems to rip out handfuls of hair and deposit them in weird places. He’s also not very open to suggestion; he’s on the debate team, and likes to make arguments like “what will make my behavior change?” I don’t know, friggin’ shock-treatment? Presumably he’s a sentient being and has some control over his behavior. Considering I go out of my way to change my behavior for the better before he ever says anything, (oops, I’m leaving water all over the counter. Guess I’ll try to keep it under my control. Hmm, guess I should’ve removed my empties from the living room before he did.) I’d say I’m not asking a lot. To his credit, he did stop leaving the communal soap wrapped in hair, but Jesus, I shouldn’t even have to ask for that “favor.”
You use “communal” soap? Ick. I do hope you each have your own toothbrush. 
Let me ammend my comment, then–he should brush his hair and properly dispose of the hair removed thereby.
Sounds like a typical roommate situation. Patience, Vampire, patience–how long 'till your lease is up?
A quick solution:
Disgusting as it may seem, collect all this stray hair for a long time until you can make it into a big ball. Then leave it on his pillow or gift-wrap it and give it to him. Maybe then he’ll get the picture.
I have the opposite problem:
I am getting sick of cleaning up my own hair, and I make a comment to Drainy about this, and she tells me that she will GLADLY clean up anything - carpets, drains, whatever - where my shedding hair is the problem.
Either that or I cut my hair and she will not have sex with me.
This is not a tough decision…

Space Vampire, I just have regular length guy hair, and I’m always cleaning it out of the sink. It’s just decent manners if you’re living with someone. I don’t see any problem with bitching to your roommate about this. (I also like Welfy’s idea.) Either that, or find out what he doesn’t like and start doing it.
The worst is - the half swallowed chunk of what ever youve been eating with a piece of hair wrapped around it. Your not quite sure, but can feel something. You stop chewing and start feeling around on your tongue for that bit-o-hair. Controlling your gagging reflex, you finally get a firm grip on the end of the “supposed” hair. Pulling, only leads you to discover that it is currently wrapped around your tongue and part of a tooth. Pulling, unwrapping, controlling your impluse to throw up, you finally dislodge the ‘chunk of food’ along with the unwanted hair. This is only worse if you discover that the hair is not yours.
Thank you so much for sharing. (BBBBBLLLLLAAAAAGGGGGHHHHH!!!)
My own suggestion is to slip him some chemotherapy when he’s not looking. If you get caught, you can always say it’s a preemptive measure, since you care about him so much.
