For those of you with bangs, what do you do about only your bangs getting greasy?

I just washed and dried my hair...

I dry my hair over there and go out.

I have an oily scalp and dry hair.

As a result

When I sweat or it's hot, oil on my forehead...

Only my bangs are greasy.

You can wipe your forehead with blotting paper or pat it on with powder, but...

Since I have wavy hair, my bangs split.

Only my bangs stick out and clump together later..

It gets greasy if you don't wash it... but I did wash mine... ㅠㅠ

I wash my hands morning and evening.

I wash my hair in the morning, but it gets greasy by the afternoon.

Do you only wash your bangs?

How do you do it?
