#i'll declare that one canon in my harry potter / glee crossover universe

Ok my actual take on the Greasecourse™ (which I’m sure everyone was hotly anticipating) is something I’ve said over and over again on this blog, which is that nearly anything can work with the right framing. In other words, you can pick basically any reason for Snape’s hair to be greasy as long as you can make it make sense within the story that you're trying to tell. There just has to be a reason (a good reason – that’s the part that gets a little more arbitrary) why you picked one explanation over another. This will probably make more sense if I give some examples

Snape’s hair is greasy because he never developed good hygiene habits due to poverty and neglect -> Emphasizes how his childhood and upbringing still deeply affects him

Snape’s hair is greasy because he has poor hygiene habits due to depression -> I’m not going to go through all the reasons this guy could be depressed, there’s literally so many

Snape’s hair is greasy because of sensory issues -> This is probably one of many ways his sensory issues/neurodivergence/autism manifests, how else does that affect him?

Snape's hair is greasy because of potion fumes -> Imo this one runs the risk of being boring if you make it sound like it’s totally out of his control... the important part would be to consider how Snape feels about and reacts to it. But depending on how you deal with that, I think you can make it work in a few ways. Maybe it shows that Snape is industrious and always working, even to the detriment of his hygiene, or it could show that he cares more about the things that interest him than he does about what others think of him... or a secret third thing

Snape actually tries to make his hair look nice, but it’s just naturally very greasy -> I quite like this one as a follow-up to the first one (the never developed good hygiene habits one). Even when he tries to do the right thing (the correct thing?), he still ends up failing lol. Emphasizes his wet pathetic side

Snape’s hair is greasy because he’s a loser and a bad person -> Well I think it’s very boring to make a character ugly to indicate that they are Morally Bad but it's certainly a strategy... sometimes it's very clear that an author is trying to make the reader dislike a character when they describe them as gross/ugly/whatever. Hell Rowling did this literally all the time (Not that that was a good thing lol)

Alright I'm going to stop myself there because omg I didn't think I would have so much to say about Snape's greasy hair. Good lord
