Ok so I've got my first greys and I'd like to cover them. I don't really do the hairdresser- it's been 14 months so I'm considering home dyes. I dyed my hair lots during my 20s but that was for the look. I also think it made my hair a better condition. Now however I'm looking to cover greys up. Any advice on product? Are they all much of a muchness? I have dark brown hair if that makes a difference and looking to stay this colour. Thank you
