Greasy/itchy scalp

Ge

Can anyone recommend some new hair shampoo for dandruff/oily hair?? Im 10 weeks and 3 days pregnant and my scalp is ITCHYYYYY and I have a bit of dandruff now. It’s so annoying, I washed my hair yesterday night and my hair is already greasy. (I made sure everything is washed out properly, it’s still get greasy) feels like I need to wash my hair everyday because of it.. 🥺😓
