I started getting mild dandruff a while back and it turned out to be scalp psoriasis. If there's anyone who has it, I hope they read this and take away value from it. The protocol described might work for other kinds of dandruff too.
Scalp psoriasis vs seborrheic dermatitis - hard to tell the difference because the symptoms overlap.

In my case, I knew it was not SD because I used prescription strength ketoconazole shampoo, making sure to let the lather soak in, and saw zero improvement. I additionally got body psoriasis but that's a different story.
Only one treatment actually worked for me I got it from this video featuring a girl who's been dealing with scalp psoriasis for a while (and yes WB):
If you have any kind of dandruff I recommend you watch the video, the girl is cute and has explanations behind all of her ideas.
Summary of the video and what I do:
1. Shampoo = Dr. Bronner's. Wash normally and do not scratch your scalp more than necessary.
2. ACV = conditioner. I douse my head in it after showering and let it sit and dry. This is the
major key.
3. Shower = not hot! Warm or cold.
4. Again do not scratch your scalp unless necessary.
5. Hot hemp treatment described in the video. I found this useful and made my scalp feel amazing but it didn't produce meaningful results to justify sitting with a shower cap on for 6-8 hours. I do this when I can but it's not a priority. I did it a few times while sleeping but I think this is what's been causing my recurring styes...
6. Coconut oil = hair gel. Religiously!
7. Shower water filter
At the end of the day, I think the ACV is what's helping my dandruff more than anything. Since I started using it I can finally go outside without coconut oil in my hair and I won't start itching. The girl breaks this down in the video, something about pH of the hair. This would also explain why using a shower filter works, if you remove all the nonsense from your shower water your hair pH will be different. I bought one from Berkey a while back and IMMEDIATELY felt the difference.
