I'd personally try zinc picolinate, coal tar, salicylic acid or azelaic acid on my scalp before BP, just because of its drying and sun sensitivity properties.
Thing is, I pretty much have tried everything of these you mentioned. The only one that has been working, at least a bit, is ketoconazole 2%. It alleviates the itch but doesn't prevent the pimples/acne. They don't itch but I end up hurting them while washing or combing it.
Hmm. There are other acne preventions but you've probably tried those too. Maybe give BP a go, but just make sure you wear a hat/use sunscreen and moisturise if you notice excessive dry skin.
Alright then. I appreciate your input!
It's too soon to call it an update, but since I created this thread my scalp is at its best. No itch, no stings, no pain, at least for a while. It's been some time since I felt this good!
What changes did you make?
I started using ketoconazole every other day as of the week I started this thread. Applied benzoyl peroxide on my face, especially forehead where I get more pimples. I also applied on some spots I had on my scalp, but only once a day at night, washing it the following morning. On Tuesday this week I started using a tea tree shampoo instead of keto, and so far no signs of itchiness. Maybe it's too soon to say I won, but I recognize that as an accomplishment since my scalp has been torturing me for months
