Bar Soap & Shampoo Bars

A $5–12 shampoo bar from brands like Ethique or HiBAR lasts as long as 2–3 bottles of liquid shampoo ($8–15 each), saving $10–30 per bar while eliminating 2–3 plastic bottles. Globally, 552 million shampoo bottles end up in landfills every year, and bar soap generates 25% less carbon than liquid soap in production and 40% less in packaging. The concentrated format means less weight in shipping, cutting transport emissions by up to 50%. This swap costs less than a typical takeout meal and pays for itself within weeks.
