Pretty much every time I have my hair coloured, I can see that my roots (which are really grey/white) still show as a slightly lighter colour.
So it would appear my hairdresser's dye doesn't do a perfect job of covering them up.
Are there certain dyes which are better for stubborn grey's? It annoys the hell out of me when I can still see a lighter shade down my parting!
Please say there are!
