Bottled liquids and gels of any kind are leakage prone, all the more so on airplanes: it's truly surprising what can be made to leak under changing air pressure conditions. Full containers fare better than those containing large air spaces; one helpful trick is to squeeze the container a little before screwing on the cap, thus giving the contents room to expand.

Better, though, is to repackage liquids and gels in more appropriate and smaller containers. Not only will this reduce the leakage problem, it will save weight and space. You are, after all, unlikely to need a six-month supply of shampoo on your two-week trip to Greece. For that matter, it is possible to buy shampoo in Greece.
