Ok so I have previously had my hair bleached at hairdressers and was lovely. Tried to do roots myself and they went ginger. Managed to tone it down but ended up with several shades of blonde. In a rush to fix it I went and used an 8 wash temp medium ash blonde and now I'm left with a green tinge to my hair lol. As I'm not very clued up on the whole bleaching process I'm thinking of just going back to red. What should I use next?
