I found this...
There are several good antifungal shampoos on the market that can be purchased without a prescription. The main shampoos are selenium sulfide found in Selsun, pyrithione zinc found in Head & Shoulders and Sebulon, coal tar found in Sebutone and Tegrin, and finally ketoconazole found in Nizoral.
All of these shampoos have a medicated smell. The way to use them is to shampoo and leave on for at least 10 minutes then rinse off. The shampoos can be used on the face and other parts of the body as a lotion with the same instructions as long as precaution is used around the eyes. Do this daily until the redness and flaking is controlled then use 2-3 times a week as needed to keep symptoms from returning.
Topical Steroids For Seborrhea
Topical steroids reduce the inflammatory response and help control itching. You can buy hydrocortisone cream 1% over-the-counter, and it's safe to use on the face. Apply twice a day to the affected area until the redness resolves. Save the hydrocortisone for flare-ups and use the antifungal shampoo for maintenance because long-term steroid use can cause side effects like acne and thinning of the skin.
I can see the throat and sinuses being related, cause and effect, but the scalp connection, not seeing it either.
Maybe you should go see a dermatologist..but not like the one I had. Cripes.
If using the hydrocortisone. Be careful..you know my experience. Still recovering from that escapade....
Glucosamine...I am confused on why they suggested it for your joint pain. It is thought it can help repair damaged cartilage from osteoarthritis. Glusosamine is not an anti-inflammatory. I give that to Riley, my dog for her knees even though it is made for human consumption.
Do you have Gerdie? How is your stomach? Could cause sore throat from the acid...
Chat at ya later....night.
I have Lupus. So *^#@! what.
