You don’t keep your toiletries safe
First of all, you have to keep all your toiletries in a zip-top bag to prevent damage. ”Don’t just put your shampoo into your suitcase and expect things to turn out fine,” said Walden. “Even if you’ve never opened it. Put toiletries in a zip-top bag! If you don’t want certain products mixing, use several different bags. Press the air out of them before sealing. Sometimes I’ll even put them inside a plastic grocery bag, too, just to be extra safe.”
