My hair needs really good hair spray. Any humidity above 50% kills the curls. Matrix's Biolage extra (firm hold) spray is the only stuff that has proven to work. I'm going to Japan in a few months and want curls, but they won't happen unless I can bring the hair spray. It's in a spay can, so I don't believe I can bring that with me on the plane (correct me if I'm wrong and I'll delete).
So I was wondering what good hair sprays are out there in Japan? I ask because I was wondering if there are any recommendations in any of the recent Kera's or GLBs.
