Usage information
All three shampoos provided usage information that is concise providing a general use of the shampoo. They also recommended usage of their respective other products such as conditioners and scalp lotion which can help in increasing sales of these other hair-related products.
Cautionary/Warning Statements
Only Head & Shoulders shampoo provided warning statements on the label. The presence of the warning statement greatly improves the safety in using the shampoo relative to Sunsilk and Clear shampoos. However, the absence of the warning statements may also signals the higher safety of using the two shampoos compared to Head & Shoulders.
Manufacturing date/Expiry date/Shelf-life/Batch reference information
Both Sunsilk and Clear shampoos provided manufacturing date information with Clear giving the additional expiry date information. Head & Shoulders provided neither the manufacturing date nor expiry date information. The omission of the expiry date information in the Sunsilk label hampers the user’s ability to determine the time range for safe usage. This is particularly highlighted since all three shampoos do not have shelf-life information. Omission of both manufacturing date and expiry date information in Head & Shoulders thus hampers any user’s ability to determine the shelf-life. Users also may not be sure if the shampoos have been produced in recent time. Only Sunsilk provided information on the batch reference which may come useful if there is any complication with the shampoo usage among its users. The shampoo’s batch could be recalled and tested for any anomaly thus improving investigations.
