Are there any shampoos that are effective for oily scalps?

I have an oily scalp, so I wash my hair in the morning and in the afternoon

Around 3 or 4 o'clock, oil starts to rise to the surface of my scalp.

It looks greasy and cakey, so I'm always self-conscious about it.

Various products good for removing scalp oil

I tried it, and it feels good the moment you use it, but as time passes...

I think they're the same.

Silky smooth hair that stays oil-free until the afternoon with just one shampoo

Isn't there a shampoo like that somewhere?
