PLEASE help....

Okay, here is my situation. My hair is pretty short, above shoulder length, the color is naturally medium to darkish brown, and I usually get it highlighted at the salon. I get a partial weave of 3 colors, a dark blonde, lighter blonde, and a light light wheatish blonde, the effect is very pretty. Unfortunately my hairdresser is 2 hours away and very expensive, I`m currently pretty broke and haven`t gotten my hair colored in quite a while (the last time was the end of September!)
Needless to say, my roots are about 4 inches long and look terrible. I am going to a fancy New Year`s Eve party and don`t want my hair looking like this. I thought of going to a local salon, but I really don`t want to take the chance on a colorist I don`t know messing me up really bad.
So....any drugstore remedy I can do for this until I can get to my salon (next month!)? I thought maybe a color depositing shampoo, or something...I just want something non-permanent to help the blonde blend in with the roots a bit better until I can get to my colorist.
Any ideas would be greatly appreciated.
Thank you!!!!

Callie, I wouldn`t go with a Self-HiLiter. You might want to go back to your original color (store bought ), Only because, if you hi-lite over what is already blond, it will turn out LIGHTER and may turn to Cotton or Break-Off. Something like this you should leave to a pro.
