Expert in colouring advice please - I’ve generally always had Anoa applied at the salon (three quarters of 5.0 & one quarter of 6.1). I’ve changed salon as moved out of the area & they never seem to get it right! (Fed up paying loads now) All I want is stray greys covered & to knock out most of the warmth! So...I’m considering doing it myself. Is it fairly easy to do the mixing side? What else do I need? Not sure whether to go Anoa or Majirel (I understand that anoa is more oil based?). I’ve Nice & easy boxed coloured years ago but whilst that covered my greys it didn’t knock out the warmth! I don’t feel confident doing a bit of both colours so what would you suggest if I had a mix of 5.0 & 6.1? TIA
