Mine Too
I've noticed my hair has gotten very dry, too (18 weeks prego). I have curly hair that tends to be dry anyway, but one tip I learned before I was pregnant is that I don't always have to wash out all the conditioner. For curly hair, leaving some conditioner in my hair kept it a little less dry. This may not work for everyone, but I usually just leave the conditioner in my hair these days.
