How do I strip these blonde highlights?

Today I put in a lot of blonde highlights. This is my third time and the last time I didn't dye it enough. I have dark brown hair and put in Revlon Frost and Glow highlights. The BLONDE is overwhelming!!! I'm a blond now!! (well more than brown!!) How do I strip the color so it isn't as intense??

rub cucumber in your hair cut it into little slices and rub it on the blonde highlights xx

Buy a toner to tone it down
Go to a beauty supply store such as salleys
and ask a person that works there
They should be able to tell you
