The Best Solid Shampoo Bars That Are Good for Your Hair and the Planet

Does looking at all of the shampoo, conditioner and body wash bottles cluttering up your shower caddy induce guilt about that growing island of plastic in the Pacific Ocean (not to mention the landfills)? Do you get annoyed trying to squeeze that last dribble of liquid shampoo out of the container? These are not great ways to start your morning — so maybe it’s time to switch to something a little old-school: Solid shampoo bars.

Shampoo bars aren’t a new concept. Before humans started to spend so much time on their hygiene (eek!), hair care hundreds of years ago involved massaging fragrant oils into one’s hair or using vegetable starch or wood ash to cleanse strands and absorb extra oil. Then, in the 19th century, soap bars containing palm fruit oil and coconut oil became popular for washing both bodies and hair. It wasn’t until the 1930s and 1940s, with the introduction of liquid cleaners and plastic products, that bottles and bottles of hair care products started taking over American bathrooms.

Fast-forward to today and we’re finally starting to realize that all of our “progress” is having some unfortunate consequences. According to a recent report by the World Economic Forum, by 2050 there could be more plastic in the sea than fish. Plus, 80 billion plastic bottles disposed of around the world each year are from shampoo and conditioner alone. Shampoo bars eliminate the wasteful packaging of liquid versions so we can help get the environmental impact under control.

Plus beyond being practically package-free, shampoo bars use natural ingredients to cleanse and moisturize your hair — and each bar generally lasts as long as two or three bottles of liquid shampoo. We’ve rounded up some of best shampoo bars for all types of hair and scalp needs. Check out the choices below and start a hair care routine that’s as good for your head as it is for the planet.
