Personal care products are applied directly to skin — the body's largest organ — and often left on for extended periods. Many contain microplastics (as exfoliants or film-forming agents), phthalates (as fragrance carriers), and PFAS (in long-wear formulations). Daily use compounds exposure significantly.
Why We Rated It This Way
Head & Shoulders is effective for dandruff but the chemical profile is concerning. Synthetic fragrances, zinc pyrithione, and virgin plastic packaging make this a poor choice for daily use. Natural alternatives exist for dandruff treatment.
