Here's a new take on your boring old shower routine: bar shampoo. It's just like bar soap, but specifically for your hair. And it leaves your hair just as fresh and clean as the bottled stuff too, with the added benefits of TSA-friendliness and plastic-free packaging. Each bar is made from natural ingredients and offers as many uses as the average shampoo bottle—and there's an available travel tin to keep it safe and mess-free when on the go.
