Please recommend scalp care products that are effective for dandruff and itching.

Are there any good scalp care products for summer use for someone with an oily scalp suffering from dandruff and itching? My scalp naturally produces a lot of oil and feels hot, causing it to get greasy quickly, so I have always focused on using shampoos with good cleansing power. However, the shampoo I recently opened and have been using seems to lack cleansing power; even after washing my hair, the oil on the crown of my head feels like it wasn't fully washed away, the itching has worsened, and most importantly, I've been getting a lot of dandruff. This is the first time I've had this much dandruff since I couldn't wash my hair for over a week after getting stitches for a cut on my head in a car accident. I had been using the gray Dentrol Deep Clean shampoo for so long that I was getting a bit bored, so I bought this new product from Mise-en-scène when it came out, but I'm so disappointed. It is the product in the attached photo, and I would cautiously advise against it for those with extremely oily scalps who are looking for a shampoo that effectively cleanses greasy scalps. Anyway, my scalp is a mess these days for these reasons, so please recommend a scalp care product that can help manage dandruff and itching. Ideally, a shampoo would be even better. I don't tend to use many scalp care products. Since I have an oily scalp, I only use treatments occasionally, and usually, I just finish my scalp care by applying hair essence after shampooing. I would appreciate it if you could recommend a shampoo or a simple scalp care product. Even if it isn't a specific product recommendation, I would be grateful if you could share any tips on effective scalp care methods for dandruff, itching, or greasy scalp!
