Is kerastase products have expiration date?

Kérastase products, like many cosmetic and hair care items, do not typically have a specific expiration date but may have a Period After Opening (PAO) symbol indicating how long the product remains effective after it has been opened. Generally, it is recommended to use products within 12 to 24 months after opening for optimal performance. However, it's essential to check for any changes in smell, texture, or color, which could indicate that the product has degraded. Always store products in a cool, dry place to extend their shelf life.
