Objectives: analyze the pH of shampoos of international and national brands. Test different products groups: professional, commercial, medical/dermatologic, antidandruff and children. Methods: record the pH of 104 shampoos sold in Buenos Aires City with portable paper pH indicator. Results: 41% of the shampoos tested had a pH lower than 5,5. 92% of professional products showed a pH lower than 5.5. Commercial, medical and antidandruff shampoos had very similar profile, 68%, 67% and 67% respectively showed a pH lower than 5,5. Children ́s products had lower pH than the other groups (except professional) instead of their no tear characteristic, 54% had a pH lower than 5,5.
