Abstract

Background: few studies analyzed the shampoos pH. Although it is not clear which is the optimal pH, evidence says it should be near 5,5.

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.

Conclusions: although there is no clear decision of ideal shampoo pH, we know that alkaline pH associates with friction, frizz, cuticular dam-age and hair breakage. It is very relevant for dermatologist to know hair care products main characteristics.
