Stop hair drying out please help

[tomanyanimals]

I am 32 weeks pregnant and my hair is incredibly greasy at the roots to the point that an hour I have washed my hair I need to put it up as it looks like it's not been washed for weeks the only thing that makes a slight difference is hairdryer and straighteners having never really used them I have heat protection spray and I condition with a mask once a week is there anything else I need to be doing as I really don't want my hair to dry out and look awful

Try a dry shampoo?

Like the skin on your face makes more oil if you overstrip it, your scalp might be reacting to the heat from the dryer and straighteners along with the increased washing.

I have the batiste but may try the other ones see if that works abit better as I only get an extra hour with the batiste.
Thank you
