It’s hard to think about self-care when the products lining your bathroom shelves are packaged in plastic containers and filled with non-biodegradable microplastics and microbeads — research reveals that 552 million plastic shampoo bottles are dumped in landfills every year, while 5.25 trillion macro and microplastics make their way to the oceans. Switching from liquid products to bars, especially with shampoos and conditioners, can thus help you do your bit to preserve the environment. That these products are also travel-friendly adds to their allure.
