Where these two actually differ

  • We flag 1,4-dioxane (surfactant byproduct), Fragrance allergen undisclosure and Bacterial or mold growth during storage on the Aunt Jackie's 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 Aunt Jackie's.
  • The Aunt Jackie's is aqueous shampoo solution, typical surfactants and conditioners 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 →
