Which GHD straightners would be best for me?

i think you should just get the normal IV styler. i have these and they are brilliant, easy to use and quick. i have thick hair but by the sounds of the explanation of your hair mine doesn't sound as thick. either way the IV styler works, it may take a little longer to get through all your hair, just do it in layers and you will have perfectly straight hair. i find the IV styler ideal to use and my friend had the IV salon styler which she got rid of because they were too big and clumsy to use.
