while im not currently in australia, (moved to germany cause of my love) i was for a few months last year there. born n raised in south east QLD i do know how bad the humidity can be. I only used conditioner.... n while its been a year now, i have forgotten what its called..... though it was all natural with alot of natural australian organic herbs and oils. annoying me that i cant think of the name, omg, im even googling it to try to find it for you
this is good i tried this: Avalon Organics | CONDITIONERS (not the one im thinking about though)
yay found it just before i was going to post this, talk about luck!
here ya go, its great, i used it manly for a leave in, (conditioner only styling here) though also as a "normal" conditioner. i got it at priceline.
Alchemy Jojoba Conditioner « Chirinka Shop
its a great find
