Holy hell, this makes so much sense!!
I absolutely set myself up to get a fungal infection...
My hair is waist length and takes many many hours to dry.
It cannot be brushed while it is wet or the strands just snap and break and the tangles get worse.
My hair chews blow driers up and spits them out, so my solution is to wash my hair before bed and let it air dry over night.
Because my hair will make my sheets wet and wrap around my neck and generally be obnoxious, I put the wet hair into a bun to sleep.
Because it is in a bun, it doesnt dry all the way through over night.
So I am basically wadding up damp, body-warmed hair for entire nights.
If that doesn't create a breeding ground for mold and fungus, nothing does.
I have been such an idiot. And you are a genius.
I am going to immediately stop letting my hair air dry over night, stop putting it in buns while it's wet, and whip out the blow drier to keep it wet as short a time as possible. If this fixes the problem, it is confirmed for a (likely very common) fungal infection that doctors have somehow missed for years. Not that I'm surprised. -.-"
Will report back.

Here is what I was going to post as reply to a lady who also mentioned that LUSH products have been helping her. So others can cross reference my info with their own.
...............
I had lush shampoo and conditioner I was using over a year ago for quite a while (loved it). Retired the shampoo when the bottle got low and switched to something else.
A year later, suddenly (like over night!) my hair is so incredibly greasy, I just cannot contain it. I mean, it is SATURATED with grease.
I threw away the shampoo and conditioner I was using when this started, since it was cheap and off brand I blamed it.
Used shampoo and conditioner I used to use lots before (at least 3 different brands) and that didn't fix it.
I tried using hardly any product to wash it, thinking I was using too much and couldn't rinse it all out.
Didn't fix it.
I tried using double the shampoo and lathering and rinsing for 5 mins each.
Didn't fix it.
Tried not using any conditioner at all.
Hair was just as greasy and even more unmanageable.
I pulled my old bottle of pineapple based Lush Rehab shampoo out, and even though it is very old now it still extremely potent, and it is literally the only thing that gives me a single half-day of respite from this constant disgusting grease! The citrus dries my scalp right out but I would rather have the odd flake of dandruff than have stringy hair so damp with grease it actally looks darker in color.
I am getting sooo frustrated. I've NEVER produced much grease at all, and suddenly my hair is constantly wet with this nasty oil.
Sometimes after I wash my hair, as soon as my hair starts drying it's greasy already.
The only thing that has changed for me is that I recently started dying my hair. About 6 months ago i'd say. I've used at least 3 different brands of dye so I wouldn't even know which one to blame if that were the problem.
I have waist length hair.
I don't over brush it. (brushing more than necessary will pull grease from your roots down into your hair - but even that would not explain the sheer quantity of the stuff).
I am at an absolute loss.
Even when I go to town with Rehab shampoo, and finally manage to get my hair properly clean, it only lasts several hours before the grease is back. I don't know how it's humanly possible to produce so much.
SOLUTION
I was having this problem, it was very sudden and my hair had a sort of waxy greasy layer on it even after showering and cleaning it multiple times. After visiting the doctor, he said it could be dermatitis of the scalp, and over production of yeast (meaning the pH balance was off).
I have found a solution that actually worked really well!
Try using an Organic Tea Tree shampoo, I got mine from the "Organics" section in the grocery store. Massage it in really well for a few minutes to get a good deep clean, then wash it out like any other shampoo.
Next, I sprayed apple cider vinegar and water solution that i made, onto my hair (1 part apple cider vinegar, 1 part water), and let it sit for a few minutes, then rinse it out. You do not need to use conditioner after this, my hair came out silky smooth and grease free! (Apple cider vinegar is awesome for your hair to begin with) You can find it at the grocery store, i once again got mine from the organics section.
I hope this helps!
I have also experienced this problem over the last few days and I may have found a diagnosis for it. If you find that you also have dandruff and dry skin on your face then it may be a type of dermatitis called seborrheic dermatitis. Have a read about it here http://itchylittleworld.com/2014/10/07/waxy-greasy-hair-after-shower-a-surprising-form-of-dermatitis/ and talk to your doctor about it. :)
I don't have a certain greasy spot...my entire scalp just feels moist and greasy lately. I have stopped dying my hair for a few years now, so I know that has nothing to do with it; I have grown my hair out long, so it's taking longer to blow dry it...I think that has something to do with it. I think blow drying too long, or maybe even because my blow dryer is old and is hotter than it used to be, causes the oil glands to be stimulated. I will try to use a lower heat setting next time and see if that's it. I also think it could be hormone related. I will pay closer attention to see if it happens only around the time of my period. I originally thought it was just a sign of getting old (43 now), but this happened to me a few times while pregnant at 38 and 40 years of age, and I would change shampoos, staying away from anything that said sleek or moisturizing. I would also yell at my older sons in the house that they better leave my brushes alone! All my boys use hair gel and then they use my brushes because they are too lazy to keep up with their own. I'm now thinking it wasn't that at all. Poor kiddos... ;)
I notice at salons when I have my hair washed (which isn't often, as I have a boatload of kids and don't get out much), that they do not put conditioner anywhere but the ends of my hair. I may try that, too...
Good luck to the rest of you!!
Hey thank you for this feed back. I am so game to try it. My problem was sudden and well.
Hi, okay so i am a high school student, and obviously in high school, you kinda wanna look your best at all times. You know everyone straightens their hair and what not. I have straightened my hair like every other day for years and it always comes out looking amazing. But all of a sudden like a few days ago i noticed when i blow drying my hair, the roots get extremely oily. I like to blow dry my hair in layers that way its easier to get each piece dry before using an iron. I have been very discouraged to wear my hair down because of the oiliness. What do you suggest i do without spending hundreds of dollars?
