How can i make yellow hair look more natural?

I have naturally medium brown hair...I have been a blonde before and decided to go back and do it again! I wanted a light blonde almost platinum...but it came out very yellow. I'd like to find out how I can make it look more natural!?
Also I'd like to...

lighten my eyebrows...they are very dark darker than my natural hair color even...what can I do to look like a natural blonde?

dear mrsmullins,

There are many things you can do but the most nautral is to put a little of a light brown into your hair or evn if you rather not do it by yourself you could go to a local hair salon and get it dyed there and the best part is that you can tell them how you would like it. so go with it.

to lighten your eyebrows use Jolen bleach its safe to use on your face. use a violet toner to remove the yellowness from your hair.

the best way would be to go to a hair salon and tell them exactly what you want. When new roots come in buy an ash or natural blonde shade of hair dye instead of spending alot of money going back to the salon.

You could use a very light ash blonde tone and add very little violet color corrector to it to remove accesive yellow. I repeat, VERY LITTLE!!! But don't just buy haircolor from any store. Go to A professional supplier like Sally's for example.
Best advice; Go to a professional hair salon.
