Wash your hair when going to the hair salon vs. don't wash it

Do you wash your hair before going to the hair salon?

Or are you going without washing your hair..!!

I'm going to wrap it up for now... haha. If I leave it too messily...

I think the hairdresser might not like it ㅠㅠ!!

But when dyeing your hair, going without washing it is good for your scalp health too.

They say it's good!!
