They’re all from Omerica Organic. :)
Before I answer, let me just say that I’m not a professional, buuuut if it were my hair I would wait until it was very faded. Do lots of conditioning treatments (it will make the red fade, plus make your hair soft!) then bleach. When my hair was red and I bleached it, it ended up a light pink.
I doubt you’ll get to a nice bleach blond after the first bleach without frying your hair though. Good luck whatever you do! :D
