Write a list of every toiletry item you plan to bring on your trip, making sure to include the name brand of each item. You will need to refer to this list often when shopping.
Consider whether you want to purchase travel-sized versions of your beauty tools such as your hair dryer. Smaller versions of these items come in handy on long trips, when you'll need to save luggage space for additional clothing items. Add any of these items to your list.
Add any other small items you made need for your trip to the list. This could include an inflatable neck pillow, an eye cover for a long flight, earplugs and a small alarm clock.
Find the travel aisle in your local discount store, drug store or grocery store. Refer to your list of toiletries as you peruse the aisles. These types of stores offer the best selection of travel-sized versions of national brand toothpastes, mouthwashes, shampoos, conditioners and deodorants.
Go to a beauty supply shop for travel-sized versions of your more high-end beauty products. Often, you'll be able to find individually wrapped skincare treatments, miniature bottles of moisturizer or fully-stocked travel kits for a particular beauty line. Some manufacturers even sell small sample versions of their products on their own websites as well.
Head to a luggage store, which can often be found in your local mall or outlet shopping center, to find small travel items such as hair dryers, inflatable neck pillows, power adapters and travel alarm clocks.
Go to your local outdoor sporting goods store for travel-sized items that are geared for outdoor travel, especially if you're planning a backpacking or camping trip. These stores have everything you'll need—from small bottles of insect repellent and sunscreen to first aid and cooking kits.
