Frequently Asked Questions About Liquid Shampoo Plastic Bottles

Common questions and answers regarding materials, care, and plastic-free standards.

True solid shampoos formulated with gentle plant surfactants (like sodium cocoyl isethionate) rinse clean and do not leave residue. Avoid traditional lye-based soap bars for hair, as their high pH can feel waxy.
