Sorry to hear you have hyperemesis. If you are not managing to eat oily fish you might ask your doctor to sanction a long chain omega-3 supplement, you can purchase triple strength fish body oil capsules fairly cheaply - I suggest the high strength because it's less to get down and hold down! This is beneficial for your baby's development as well as your own health.
You could get a proper diagnosis for your scalp issue whilst you are meeting with your doctor, it's unwise to self treat based on self diagnosis especially when pregnant.
