Help My Hair!!!

For those of you who don't know, I just barely moved from Oregon to Virginia and I have encountered two problems with my hair. One problem I expected, the other I did not. Problem number one-I have naturally frizzy hair by nature. That combined with humidity and it is a bit of a disaster. Anyone have a frizz product that they swear by? It would be great to have something that works when my hair is curly and something that works when I want my hair to be straight. (Although, I might have to give that up for a while if I can't find anything to help.)
My second problem is the worst. I am used to getting out of the shower and running a pick easily through my wet hair. Its never tangled or knotted. It just easily slides down. Since I moved into this house, when I get out of the shower my hair is a tangled mess. It takes me ten minutes to comb through it, section by section. Its really awful and I am not sure why it is like that. My only guess is it has to be the water. I can't really figure out anything that could make that big of a difference. I am using the some conditioner I was using before I moved. I even bought a new bottle just to be sure. Does anyone have any idea what I can do for this or any idea of what could be causing this besides the water? If I can't fix it I might just buzz my head one day so please help!
