If you're trying to travel light (which is what the Hand Luggage Only project is all about), keeping your washbag trim is a key strategy. But how can you do that effectively and still stay clean, healthy and presentable?
First, a disclaimer. Although any trip involving an overnight stay is going to involve some sort of washbag, I don't think it's possible to come up with an absolute list of stuff that everyone needs — or doesn't. Lifehacker commenters have tended to agree, as an argument about aftershave early in the HLO project demonstrated pretty neatly. So what follows isn't so much a prescriptive list as a discussion around the kind of broad issues you need to consider if you're trying to put together a collection of travel toiletries.
Whatever list you come up with, one important point that most regular travellers (especially in a business context) tend to agree with is that it's worth maintaining a separate travel washbag, rather than just grabbing items from your bathroom before you leave. This saves time on packing, reduces the odds of forgetting something, and lets you keep smaller supplies for use on the road if that's what you prefer. Just make sure you remember to restock as needed at the end of each trip, lest you end up in Brisbane with a dried-up deodorant stick.
The bare essentials
My own 'bare minimum' travel kit would consist of deodorant, toothbrush, toothpaste, razor and shaving stick. People not fussed by facial hair could presumably skip the last two. Feminine hygiene products would feature as a compulsory requirement for many female readers.
What gets added next depends on your personal preferences and what you can reasonably expect your accommodation to provide. Even the most bargain-basement hotel provides soap; most (though not all) provide shampoo. As such, I rarely pack either.
Your destination may also be a factor; in highly sunny locations, sunscreen is an obvious essential, while if you're heading to Australia's north, a mosquito repellent is vitally important. Any medications you take regularly obviously also need to go in. Many people advocate travelling with aspirin or the like for emergencies, but I tend to stick to the "if I get sick I'll find a chemist" view.
There's any number of other things you could add — make-up, mouthwash, skincare, floss, toothpicks, lip balm, eyedrops, hand cream, spare razors — depending on your own needs. But do resist the urge to replicate your entire bathroom if you can.
What you store them in is also a matter of overall volume and personal preference. I like to keep my items in a single bag that's small enough for carry-on, and which I can add to a largely-packed bag at the last minute. Being something of a cheapskate, I often recycle the washbags offered on international flights, though these have become much meaner in recent years.
Midget or not?
One popular strategy for minimising the room taken up by items is to purchase mini travel-sized toiletries. These are often sold at stupidly jacked-up prices at airports (if you're budget-minded, Big W also carry a pretty large selection these days). If you want to save money, you can collect miniature bottles and create your own portables. This is fiddly, though, and won't work for toothpaste or deodorant.
Personally, I'm in two minds about this whole approach. Quite aside from the cost factor, miniature toiletries inherently limit the length of stay before you have to replace stuff. For many categories (like deodorant), even the standard-sized options are pretty good.
Liquids and aerosols
One reason mini-toiletries have grown in popularity is because of the rules governing the transport of liquids on flights. On international flights out of Australia, you can't carry anything in hand luggage that measures more than 100mls in size. To date, similar rules haven't been imposed on Australian domestic flights — but you should be aware that they do apply in many other overseas destinations (including Europe and the USA).
Because I often travel to both locations, I've tended to apply the 'stay under 100mls' rule where possible, though not to the extent of customising my own toiletries. Instead, I've chosen non-liquid options (soap instead of shower gel; a shaving stick instead of cream; dry roll-ons instead of aerosols).
Australian domestic airports are getting increasingly fussy about aerosols. While these are still generally allowed on flights, if they're in your hand luggage you may be asked to screen them separately, which can be a nuisance if you've packed your luggage precisely.
Random product secrets
As the picture shows, two of the items that feature (perhaps improbably) in my own washbag are the Mennen shave stick and a cheap generic tube of toothpaste. The shave stick — basically a specialised kind of soap that doesn't dry up on your skin — is the most compact option I've found for my shaving needs, and avoids the aerosol dramas discussed above. (King Of Shaves make a similarly compact oil, but for me it just doesn't do the job.)
The generic toothpaste has a simple advantage over all the market leaders: it has a screw-on cap, not an attached lid. In my experience, the latter are rather more prone to popping open unexpectedly, especially in a tightly-packed bag.
