I'm worried about scalp acne (pimples)~

I'm really worried because I keep getting pimples on my scalp.

It especially occurs frequently on the bangs, and it is painful because it stings and itches every time I wash it.

I have a sensitive scalp, so I use mild shampoo, but it doesn't work.

I sweat a lot and shower twice a day. Is that actually irritating?

If you scratch it, it gets worse, and if you leave it alone, it gets itchy and you end up touching it again.

It's really tiring because when I think it's gone, it appears again somewhere else and repeats itself.

Could it get better if I change my lifestyle or products?

Anyone with similar experience, please give me some advice.
