The short answer: Eventually, yes, though not in a way that's usually dangerous. Standard shampoo is a cosmetic product, and the FDA doesn't require cosmetics to carry an expiration date. Medicated shampoo, the kind that treats
The short answer: It depends on what kind you have. Cosmetic mouthwash, the kind that just freshens breath with no other claims, isn't required to carry an FDA expiration date and holds up for a
