A review of a selection of solid toiletries that will help you avoid the ambiguous carry-on liquid regulations on flights connecting to the US. I think it’s best to just buy in small quantities what you need at your destination.
These products will help you breeze through the airport without making a stop at baggage claim. They’re all carry-on safe, and none of them have to fit in a Ziploc.
Solid shampoo and conditioners work like bar soap for your hair. Just wet them and rub against wet hair. Before repacking, set them out to dry.
