Advice on my new colour please?

I really like the colour it is.
What processes has it already been through?
You can definitely add highlights, but your base looks to have a lot of red in it, so if blonde is your goal you may be better off waiting and giving it an all over bleach first.

Yesterday I used JoBaz and today a Schwarzkopf colour mask (permanent toner/lightener), then I made a toner with a few drops of red adore as it was still really green. Before I stripped it, I had dark roots and the rest was a mix of brown/ginger/red where I'd bleached brown dyed hair to go bright red, kept that for 6 months and then put brown on it again as I needed to tone it down with only a day's notice. It did come out really brassy with some major green tones too, I was amazed that the red was removed so well. The colour now isn't terrible, it's a lot more even and neutral thanks to the Schwarzkopf mask but I just don't think it suits me. Maybe cos I've never been anything resembling blonde so it's very weird!
