How to treat this dry scalp or dandruff (?) issue

Fiorella • Soon to be mom of 2

So I’m 16 weeks pregnant and my head has been soo itchy and the dandruff is ridiculous. Ive never had this problem, like ever. I have curly hair 3b-3c hair and I normally wash my hair once a week and I would be ok, but as of the last two week dear lord. Help!! What can I do besides washing it twice a week or more.
