The Best, Zero-Waste Shampoo Bars for Every Hair Type, From Oily to Coily

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)

Best for Dry and Frizzy Hair: Kitsch Castor Oil Shampoo Bar ($13, was $17)

Best for Thin and Oily Hair: Ethique Volumizing Shampoo Bar ($16)

Best All-in-One: Auromere Ayurvedic Shampoo Bar ($8, was $8.50)

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!
