Anyone else have really greasy hair since they became pregnant?

I usually wash my hair only three times a week and wash at night before bed. Now my hair is greasy the morning I wake up after washing!

This is the very first pregnany symptom I noticed. (Plus acne on my normally clear complexion). It started a week before my period was due. I just found out I am pregnant (yesterday) so I figure this has to ve the cause!

I guess I will have to start washing (and drying :( ) every morning now. Any product recommendations?
