Here are some checklists you can use. The tally will include what you're wearing and carrying to set out. Aim for the low estimate, but really limit yourself to the high estimate. Replacements are available if you're not too picky about brands. Tubes travel better than bottles.
Full bottles leak less than partial bottles due to air pressure changes.
For anything you can't live without, either carry it close to your body at all times or carry two, in two different places. So to use appliances from home you would need to also pack a voltage converter and plug adapters. However, our voltage converters broke and broke our radios while they were at it, so we don't recommend them. Dual-voltage hair dryers, if you need them, work fine and are cheaper than the converter anyway, though you may still need plug adapters. It's probably best to plan to do most of your own laundry by hand, so you'll want to bring the appropriate supplies.
