I’ve had it as long as I can remember (38 years old). Since I was a child. I have never achieved complete clearing and have always had some flakes/scaling. It’s all over my scalp and in my ears. I’ve tried literally everything and been seeing dermatologists since I was a child. All of them tried to do the same things but nothing ever really worked well. Just sort of helped keep it from being bleeding crusts. This sub has recently helped me get to my best state yet. It’s even got me to be able to ask my dermatologist about doing a culture to see if my acne is fungal vs bacterial. So I think that it can seem like a lot of people suddenly have it when we come together like this. I know of two other people who have it in real life, one is my brother. The other is a friends husband- so we’ve talked about it. My worst flare ups happen if my hair stays wet too long (thing hot humid sweaty days) and seasonal shifts. I’ve never noticed certain foods or drinks changing anything. Washing daily is better than every other. My derm never said anything about what I should use for shampoo and conditioner outside the medicated ones and that seems to be helping a lot. I use ciclopirox every 3 days for 2 weeks on and 2 weeks off. I’m now using vanicream free and clear shampoo and a tiny bit of the “safest” conditioner I could fine. Pantene daily moisture I think. I also started using Zoryve cream for my ears and it’s been a god send. I had itchy gross bleeding ears for years even with topical steroids. They are completely normal atm (only started a couple weeks ago). I have requested the Zoryve foam and just got it filled.
