Thinking about making the switch from traditional bottles to bars? These top-rated products will help the environment—and give you gorgeous hair.
You’ve heard the phrase a million times: “Reduce, reuse, recycle.” But recycling still involves plastic production and energy resources for the recycling part. One easy way to cut down on single-use plastic and reduce your carbon footprint: Ditch your regular hair-care products that come in plastic bottles and switch to the best shampoo bars and conditioner bars.
“Using these products causes a reduction in plastic and a reduction in fossil-fuel use,” explains Jennifer Brandon, PhD, a senior scientist at Applied Ocean Sciences. “It takes a lot of fossil fuels and energy to make plastic shampoo and conditioner bottles—plus, plastic is itself made out of fossil fuels.” What’s worse, Brandon estimates that only eight percent of discarded plastics end up being recycled. “And the caps and pumper tops are often made of a different plastic and cannot be recycled,” she adds. Bars, on the other hand, are usually packaged in recyclable and biodegradable paper.
While you might be nervous to try something new in your beauty routine, don’t be. These eco-friendly products work just as well as their liquid counterparts, say experts and happy customers. Here’s how to use them: “First, get your hair completely wet,” says Julia Papworth, hair department lead on the CBS show S.W.A.T. “Then get a great lather going with the bar and your hands, and transfer it to your hair.” Repeat the process if you love suds. They bars are cost-effective, too. Papworth says that most bars can last anywhere from 75 to 100 washes with proper storage (atop a soap dish so they can air out, not sitting in a puddle of water).
So, what are you waiting for? Find out which top-rated natural beauty brands will clean, condition, and outright pamper your hair in a way that makes you feel extra good every day. Try them once and you’ll never go back.

It works amazing—I just give my beard a few rubs, and it lathers up and perfect every time. After a month, we have hardly made a dent in it. Honestly, I think that we will be saving a bunch of money because we will be using less.”
