Is washing my hair twice a day really bad for my scalp?

I have a lot of oil on my scalp, so if I wash it in the morning, it gets extremely greasy by the afternoon.

But if I wash my hair in the evening and don't wash it in the morning... it's a total mess with greasy hair in the morning ㅠㅠ

In the end, I wash my hair once in the morning and once before going to bed.

But I'm worried because I think I read that this isn't good for the scalp.

Does anyone happen to know about this? I'm worried about how to take care of my scalp.

Will it be okay to wash my scalp twice? Please let me know how to care for it.
