Buy shampoo bars
We all know that most hotels offer essential hygiene products such as shampoos, soaps, and conditioners. Still, some people prefer to bring their own when they travel. Unfortunately, these items always take up a ton of room. So, instead of filling up your luggage with bath product bottles, invest in shampoo and conditioner bars to save up space.
These little marvels smell lovely and look like soap bars. You can find them at specialty stores, and they often come in a handy travel tin. Moreover, if liquid restrictions are a problem for you, you can sort it out with shampoo and conditioner bars. Apart from that, they also reduce the risk of a mess inside your case while saving the planet.
