Where can I find mini bottles of John Frieda hair products?

I use Brilliant Brunette [by John Frieda] hair conditioner... the thing is, i'm going on vacation in a couple weeks and I'm brining one bag - a carry on. For this reason, I can not bring any bottled liquids that are more than 3oz in quantity, that means I can't bring my conditioner, because its a huge bottle... does anyone know if they sell this conditioner in small bottles??
