Does Biolage shampoo have PFAS?
PFAS Authority is a scoring system, not a laboratory. We do not test products ourselves. Grades are model-based, built from published ingredients, materials, certifications, brand disclosures and third-party lab results where they exist. See the rubric.
We graded 8 Biolage shampoo products, averaging Excellent (75/100). 8 of them grade Good or better. Against the other 27 shampoo brands we grade, where the middle brand sits at 75/100, Biolage is about typical, scoring above 44% of them.
