How should I care for a sensitive, oily scalp?

This is a story about my husband. He has an oily scalp and his hair gets greasy quickly.

However, since they had to go to work early in the morning, they dried their hair roughly before leaving. Then, they dried it thoroughly with hot air.

Maybe that's why my scalp is covered in dandruff and dead skin cells, and it is always red. First of all... Scalp care one method I was supposed to use this dandruff shampoo. I used to ask at the hair salon and buy it to use, but the redness isn't calming down easily.

However, my scalp doesn't itch or develop any skin problems. I just always have a slight burning sensation, dandruff, and dead skin cells. So, rather than intensive care, I think I've managed it with a daily shampoo. I use a shampoo that cools the scalp and deep cleanses oily scalps. And I scrub it in with a shampoo brush. But since the relief is only temporary, my scalp is red, and on dry days, it feels like snow has settled on my shoulders.

I heard the Red Ginseng Scalp Scaler is famous at Daiso, so I bought it to try removing excess oil, dandruff, and dead skin cells from my scalp. I do use scalp care serum occasionally, but I find that I have to apply it myself for it to stay in good condition. Scalp care methods I'm asking because I don't know where to start.

Should I start by soothing the reddened scalp without touching it any further?

Is there a hair soothing mist that lazy men can spray frequently? Of course, since I have an oily scalp, I want something refreshing.

Such sensitive oily scalps Scalp care methods I am wondering how best to manage this.
