Another frizzy haired girl here as well It seems the lighter my hair is coloured, the harder it is to maintain. I do what Beck has just said, I wash only at night time, I NEVER blowdry my hair, and I straighten in the morning. I too hair a GHD (well 3 now), it's the best thing I've ever bought! It's taken a bit to find the right shampoo & conditioner for my hair. I also use a treatment every 2 weeks and I use a straightening balm before using the straightner.
