If you've done all or most of this, see a doctor, could be a skin condition called rosecea--and there are topical medications.
Okay, I don't think this is diet. First, are you using an astringent such as hydrogen peroxide, witch hazel, whatever after you shave?
Second, are you changing your pillow cases regularly, not less than once a week--and that pillow, when was the last time you bought a new one?
Third, use some benzoyl peroxide lotion, about 1/4 teaspoon and hydrocortizone lotion [lotions not cremes--the lotion is absorbed and leaves the dome non-greasy],
same amount after shaving before your after shave balm--needless to say, without any oil? Are you using an exfoliant rub or a loopha sponge when you shampoo? Also, are you washing that dome two or three times a day with a mild, non-oily anti-acne soap?
There are also oral meds you can take. You might need them at least on a short-term basis to get that cleared up. I'd contact a dermatologist right away and get it seen to. They can find something that will work a lot quicker than you will on your own.Good luck.
In addition to what Saintc and Razor has recommended to you, (plus other forthcoming valuable input from other SBG members as they offer their suggestions and advice) IMHP, it seems that you may be trying to shave too close to the skin and your skin just can't handle that right now and you're not giving it a chance to heal. Give your skin a little breathing room.
I would guess (from your photos) that you are shaving every day and against the grain. Try shaving every other day and only with the grain for a week or so and so that your skin can start to heal.
Standard Electric Razors generally won't shave you as close as a blade razor, but it they will allow you to maintain a decent sly look while your scalp is on the road to repair. (The Conair CleanHead is a great alternative to manual razors - NO nicks, cuts or irration while giving you a nice, smooth, clean, close shave - More info on the CleanHead here --> http://www.iknowheads.com. Once there, click on the "How To Use" link at the top of the page to see a demo).
But all hope is not lost. You CAN make it over this "hurdle", just as I have, (and countless other SBG members also)
BTW, how often are you changing the blades on your Fusion? Sometimes we fall into a situation whereby we try to get "one more shave" from a dull blade and 9 out of 10 times, we end up with a scalp full of nicks, slices, cuts, and lots of skin irritation.
I don't know how old the actual pillow is, but I generally wash my bed sheets and pillow-cases once a month!
