How can i get hilary duffs hair colour?

I absolutly love Hilary duffs baby blond hair colour! i am dying my hair soon and i want it to be as close as possible to her baby blond look. Any ideas on a box colour i can get to look just like that? mabye even a good brand? my hair is very thick and has damaged ends already, so i need a hair dye that isn't going to damage my hair. Thanks!!
