3. Shampoo and Conditioner Bars

Ditching bottled hair products in favor of shampoo and conditioner bars is a smart way to reduce plastic waste. These bars often last as long as two to three bottles of liquid shampoo, offering comparable cleansing and conditioning power. Brands like Ethique and Lush offer a variety of scents and formulas. Store bars on a draining dish to keep them dry and extend their lifespan.
