Shampoo Has a Secret Expiration Date… Are You Still Using It? Find Out Before It’s Too Late! Your shampoo bottle might look innocent, but inside could be a hidden danger—an expiration date you haven’t checked. While most people focus on kingsize bottles, fresh scents, or bottle colors, many overlook an often ignored detail: every shampoo product has a secret expiration date that impacts effectiveness, safety, and your hair’s health. Are you still using last season’s bottle without knowing? Read on to learn why your shampoo’s shelf life matters—and how to avoid hair damage, bill losses, and wasted products. ### What Is the Expiration Date on Shampoo? Contrary to popular belief, most shampoo products don’t legally require an expiration date on every bottle. However, the “best before” date, typically printed inside or on the label, indicates when the formula and preservatives remain effective. Over time, surfactants, botanical extracts, and essential oils degrade, losing their intended cleansing power and potential risks—like irritation, bacterial growth, or reduced performance.
