Her hair colour, imo, is wrong. It's too vibrant and false looking. Perhaps she had red hair in the past. She has very fair colouring which might suggest this. However, the present colour needs to be toned down to a lighter hue. It seems she is trying to have that 'cool looking older woman' look, but it doesn't work for her (or anybody!). Her hairdresser should make some suggestions, I think. Strawberry or apricot blond would be a good way to go and the roots wouldn’t stand out so much as they do now.
