So I have brown hair, but since may I've been to my hairdresser 3 times and highlighted blonde all three times. Now it's mainly a yellowish blonde with some brown throughout, not much brown but it's definitely not 100% blonde either. Well I bought John Frieda foam just now in a brown color that has no red undertones. It has been 7 weeks since I last had bleach put in my hair, almost 8. can I put this color on my hair without worrying? Or turning green?

It will still turn green, you have took the pigment out of you're hair permanently, you need to dye you're hair a light red, permanent or semi, then dye it brown
