Will lauren conrad's hair color work on me?

i have naturally light brown hair, but have been dying it really blonde forever. i really wanna try lauren conrads hair color. the sorta dark dirty blonde. my hair's pretty damaged from all the blonde. do you think it'd completely ruin my hair to go her color? i'd get it done professionally. oh and could anyone tell me what color it is really? i think i'm going to bring a pic to the stylist but knowing the color would be nice too. thanks (:
