Help!! Hair turned out too dark!

I dyed my dark blonde/light brown hair with Clairol Nice 'n Easy Natural Dark Brown.  I wanted it dark, but it came out too dark - like Ashlee Simpson's former haircolor, which is too much for my lighter complexion.  I am probably going to my salon tomorrow to have them tone it down. 

If I wash my hair several times today/tomorrow with a clarifying shampoo, will the color fade?  Or would it be better to go straight to the salon?

Thanks much for any help!!!

I mistakenly had my blonde hair coloured very dark last year and it took about a month for it to fade to a nice light brown colour, and I was using a blonding shampoo on it.

You should be able to get highlights on it at the salon to lift the colour a bit.
