Plastic shampoo bottles sit in your warm, humid shower for months. Heat and moisture accelerate microplastic shedding from the bottle into the product inside. The scalp is highly vascular — products applied to it absorb quickly into the bloodstream.
Why We Recommend This Product
HiBAR uses no plastic in the product or packaging. The bar is formulated without silicones, sulfates, or parabens.
