Renée's Take · Jun 2026
How I Tested 8 Shampoos
I tested 8 shampoos from 8 brands across 7 safety checks, including Hazardous Preservatives (Formaldehyde-Releasers / Isothiazolinones) and Ethoxylated Sulfate (1,4-Dioxane Contamination Risk). Every product was scored the same way: material safety first, then real-world performance and ease of use.
What I found: The top picks pass third-party safety verification and hold up in everyday use. The shampoos I left off had unverified material claims, missing certifications, or hidden tradeoffs that matter day to day.
