Horrible dry scalp and face

So pre pregnancy I never really had an issue with dry scalp or face (even in the cold winter months ). Within the past few months , my scalp had gotten super dry to the point that it’s flaking and it’s so embarrassing ! It doesn’t itch , it’s just dry skin mostly around my hair line . My forehead and cheeks have also become super dry but cetaphil lotion does help with that . I switched to a coconut oil shampoo in hopes that it would help during this time , but it hasn’t . Anyone else have the same issue ?
