I finally went to the hairdresser (not in U.K.) last week and saw the same person I always do. I noticed when she took the fools out it looked a bit warm and now a week later it just looks a bit dull and dark and a bit ginger. Is there anything I can do to brighten it up? I usually have a fairly light ashy blond mixed with a darker blond. But this time it’s a dark warm blond and a really warm lighter blond. All I can think is that she didn’t leave the foils on long enough?
