Where these two actually differ
- We flag Formaldehyde-releasing preservatives, Fragrance allergens and undisclosed components, Surfactant irritation to scalp and eyes and Emulsion instability and bacterial growth on the Cantu and not on the Credo Beauty.
- We flag Fragrance allergens or undisclosed fragrance components and Mechanical irritation from crystal size and shape on the Credo Beauty and not on the Cantu.
- The Cantu is water-based shampoo/cream emulsion where the Credo Beauty is salt crystals, mineral-based scrub, which is most of the difference in these two grades.
- The gap is 25 points, wide enough that this is not a close call, and the Credo Beauty is the one to buy.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
