Toiletries on a Carry-On: What and How I Pack
Simplify your toiletries routine with carry-on-compliant liquids strategies, solid personal care options, and compact storage tips.
Packing Toiletries in a Carry-On
Navigating liquids restrictions at airport security can be frustrating. By switching to solid alternatives and decanting essentials into reusable travel containers, you can pack a full personal care kit while staying compliant with security rules.
1. Master the TSA 3-1-1 Liquids Rule
For carry-on luggage, liquids, gels, creams, and aerosols must be packed in containers of 3.4 ounces (100ml) or smaller. All containers must fit comfortably inside a single, transparent, quart-sized, re-sealable plastic bag.
2. Switch to Solid Toiletries
The easiest way to free up space in your liquids bag is replacing liquids with solid alternatives:
Solid Shampoo & Conditioner Bars: Compact, long-lasting, and completely free from liquid restrictions.
Toothpaste Tablets: Dry tablets that foam up when brushed with water, eliminating the need for gel tubes.
Solid Lotion & Perfume Bars: Compact hydration without risk of messy bottle leaks in your luggage.
Stick Deodorant: Solid deodorant sticks do not count toward your liquids allowance.
3. Decant Your Skincare Essentials
Avoid carrying full-sized products. Reusable silicone squeeze bottles or contact lens cases are ideal for carrying just enough face cream, eye cream, and foundation for a multi-week trip.
