Curly hair is plagued by the f-word: frizz!

Ok, so it looks like I am in fashion at last - sporting both red and curly hair - so should be happy and walking high on my four inch stilettoes. However, I'm having a bad hair day that is lasting weeks! I've still got my curls but I'm being plagued by the dreaded frizz and it doesn't matter what I put on my hair, I can't seem to get rid of it. So, what's a girl to do? The more product I throw at it the frizzier and flatter it gets; not enough product and it resembles cotton wool. Is it the change of the season, I wondered? With the sun coming out I've got more than just my wardrobe to worry about. I've tried everything - Morrocanoil, curl fluids - even my old faithful Aveda Phomollient isn't having any effect. I want to look more like Florence Welch than Zippo the Clown!
