Too many showers or what?

Hey, so my skin is starting to become extremely dry in places. My neck and under my boobs especially. It hurts so bad. It’s starting to crack even though I put lotion on. I take 2 showers a day 5 out of 7 days because I work at a pizza place at night and feel super greasy and I always take one in the morning because I sweat in my sleep and I don’t wash my hair at night. I’m just wondering what it may be. It hurts super bad.
