Below: Look at the expiration date. IF it is past that date, it will not be effective.

Details matter: Do you have tinea versicolor? How do you use the shampoo? No harm in using it . It will be effective for several years after the expiration date. How effective last time? If it works well, consider using daily in the shower for several years.
