Sick of single-use plastic shampoo bottles cluttering your shower shelf? U.S. landfills have it worse; they collect 552 million shampoo bottles a year (and that's not counting conditioner and body wash bottles). I was an early adopter of shampoo bars, but their lack of lather made me rule them out before I gave them a fair chance. Fast forward to the present day, and shampoo bars have come a long way. Even the most natural, vegan, pure shampoo bars generate tons of suds — and unlike bottled shampoo, they generate zero waste, as most come in recyclable, plastic-free packaging.

The 5 Best Shampoo Bars

Best for All Hair Types: Zero Waste Store Shampoo Bar ($13, was $16)

Best for Wavy, Curly, and Coily Hair: EcoRoots Moroccan Oil - Zero Waste Shampoo Bar ($13)

Shampoo bars are formulated to address all kinds of hair textures and types, including thin and oily, curly and coarse, or dry and damaged. My favorites don't contain any of the chemicals notorious for drying out hair — things like sulfates, parabens, and SLSs. They contain deeply hydrating and nourishing ingredients like Moroccan oil, cocoa butter, and shea butter. They also use some of the most delicious-smelling essential oils — scents like citrus, spice, and florals, to name a few. And they're all cruelty-free.

Once you get on board with the waste-free, travel-friendly simplicity of shampoo bars, there will be no turning back, I promise!
