I also have seb.derm. The only thing that seems to work for me is something made by Bass and Boney, for rosacea. I have both conditions, but the "salt block" actually works better for the sebborhea than it does for the rosacea. It takes a few days, but then it totally clears it up.
I forgot to add that moderate exposure to ultaviolet (e.g. sunshine) can be beneficial but overexposure makes my problem worse.
I'm a sufferer not an expert so I can only tell you what works for me. Dandruff shampoos remove my scaly skin, often leaving redness and "tight skin".
Creams such as HC45 (1% hydrocortisone) and Betnovate (1% hydrocortisone) control the flaky skin, making it normal. However, these work only for a few weeks or months before the problem returns. Also excessive use results in "thin" skin and bleeding. They should be used very sparingly and preferably not near the eyes (although I don't have much choice!) I also use Dovonex (softens the skin and loosens flakes) and Dovobet (Dovonex with added hydrocortisone). I also use Trimovate (hydrocortisone plus an antifungal and an antibacterial agent) on really bad patches occasionally. Finally, I've used Dithro cream. This helps to combat the underlying problem (overproduction of skin cells) but it MUST be washed off after half an hour, otherwise your skin turns brown.
For a couple or so years I have had a quite itchy scalp. I saw a dermatologist and he says it is dermatitis. I used a foam steroid which really didn't help at all. Have used oral steroids, didn't help. So, what helps? is my question? I switch shampoos as I feel this is causing my head to itch as wehere my hair falls is also where my shoulders burn and itch . My niece has also been complaining aboout the same problem and she is very young, barely into her teens. Would appreicate any imput into our itchy scalp problem. Around my face also itches! Help!!!!!!
I suggest you treat this with a low-potency hydrocortisone. The books say that anti-fungal creams like keoconazole and Selsun work, but in my experience they don't. Exercise makes redness redder for a while, but doesn't make the overall condition worse. Perspiration makes the redness redder too, but that doesn't mean anything either. All you need is a more effective treatment, and then you'll only have to use it once in a while. Ask your dermatologist.
Best.
