My hairdresser just told me I have to have it cut into a pixie style as it is too damaged to do anything with. 
I know I've abused it with dye and styling over the years. But I really couldnt have a pixie cut, I've got an ugly birthmark on my scalp, and a large face and large features.
In the past I've managed to get it a bit better with pregnancy pills, hemp oil and eating loads of almonds. I'll start that again. Anything else anyone has had success with?
