I need some advice help me! Naturally I used to have mousey hair with highlights which always suited me. The thing is now I'm about 50% grey so for last few years been having whole head tinted a dark blonde colour (8? shade) at hairdressers which looks lovely..... until 3 or 4 shampoos later! It gets lighter and lighter but turns a slight orangey/ yellow colour. I want my hair to be a similar shade to..... let me think....felicity Kendal but am looking more like Joanna lumley (sorry Joanna)! Any advice greatly received!
