Acne and greasy skin/hair

I’m currently 7 weeks pregnant and oh my god is my skins and hair horrible. I wash my hair every other day and it is still just so greasy. Same with my skin, I wash it every night and morning then moisturize. But I have acne all over my face which has never been an issue for me, even with my last pregnancy. Any tips? Any advice on what to change or what to switch?
