I have thinning shoulder length light brown hair with a lot of white coming through at the front. I have been using L'Oreal Excellence Creme No. 6.0 light brown which claims to have 100% grey coverage but there are still some white hairs visible after I dye my hair which is annoying as I then have to use Colour WoW powder to disguise the white hair.
I want to completely cover the white hair and have multidimensional colour (not a flat processed dyed look if that makes sense). I can't afford the hair dresser as I'm having to colour every 4 weeks because of the white coming through.
What am I doing wrong? Would L'Oreal Prodigy Permanent Oil Hair Colour or Garnier Olia work better to cover the white hair? Any suggestions welcome!
