Try a shampoo bar
This next hack not only saves space, but it also reduces the risk of a mess inside your case, and it saves the planet! What more could you want from a packing hack? Instead of opting for the bottle of shampoo stuffed inside your suitcase, and the possibility of it leaking all over your new holiday clothes, why not try this.
Switch to a shampoo bar. These little marvels look just like soap bars and sometimes come in a handy travel tin. You can get shampoo ones, conditioner ones, and even shower gel equivalents. They save space, and they smell gorgeous.
