Plastic shampoo bottles contribute to microplastic pollution but have lower direct exposure risk since the product is rinsed off. The bigger issue is the bottle itself degrading in your shower over time.
Why We Recommend This Product
HiBAR uses no plastic in the product or packaging. The bar is formulated without silicones, sulfates, or parabens.
Chemical & Health Analysis
HDPE additives (antioxidants, UV stabilizers)
High-density polyethylene bottles contain processing additives that can migrate into liquid contents over time, particularly when stored in warm bathrooms. These include Irganox antioxidants and UV stabilizers with unknown long-term health effects.
Microplastic contamination
Liquid shampoo stored in plastic bottles can become contaminated with microplastic particles shed from the container walls. These are applied to the scalp, where absorption is possible.
