Hi
When I used to get PMS - I would sometimes get dry flakey patches of skin on my scalp. (Sorry I know this is probably TMI - but I need some advice!!!). My hairdresser told me it was likely to be hormonal and not to worry. I used to use a tea tree oil shampoo (Paul Mitchell one was very good) to get rid of it.
And - now its back!!! 

As we are only at 7 weeks - I still want to be extra careful, and have read that tea-tree should be avoided when pregnant! Does anyone have any other ideas that I could research or look into....I really dont want to have to go through the next 8 months worried about dandruff!!! I am supposed to be GLOWING!!!!! 
Thanks!
Sam
