Please recommend a good scalp scrub for exfoliation.

I have a lot of concerns because my scalp tends to be a bit messy.
Maybe it's because I have oily skin, but my scalp seems to be very oily as well.
I have some skin troubles and tend to have a bit of dead skin buildup.
So I'm also trying out scalp scrub products.
I tried the René Furterer scalp scrub.
It is a gel-type scalp care scrub product.
It was a clear gel with granules inside, so it felt cool and refreshing, which I liked.
When I used a scalp scrub, it felt like the dead skin cells were also being removed.
I definitely felt refreshed.
Please recommend a scalp scrub product that is good for managing skin troubles or dead skin cells.
