I went to the hairdresser yesterday for a root touch up to cover my grey hair. Happy with the colour but not all the grey hair is covered!!!! I told the hairdresser the grey hair was still visible and her response was it was normal as we’d gone a bit lighter than before it wasn’t really grey it was just lighter!!! First thing my husband noticed was the grey hair so I know it’s not just me. I Java massive patch of grey hair on top I’m so annoyed what should I do now ?
