Anybody suffer from really bad dandruff?

Since becoming pregnant I noticed my dandruff became worse I’ve always had dry skin problems like excema especially in colder weather. Anyways I developed dandruff and I have been washing my hair with dandruff shampoo for months and I still have it it’s not super bad when you can see it but I have to brush to make sure I get all the flakes off and it’s horrible i have been thinking about going to the dermatologist but just want to see if any of y’all have used anything to help stop dandruff. I know it’s embarrassing so please no rude comments I hate it as much as all of you do lol
