Can I date a Je l'aime refill from the pump bottle?
No. Use the refill pouch's own marking. Refilling does not make its contents share the original bottle's production history.
Je l'aime Hair-Care Lots | Layered Bottles and Refills
Je l'aime is KOSÉ Cosmeport's hair-care brand. Layered, Relax and iP are different ranges, while shampoo, hair treatment, hair mask and booster oil serve different roles within the routine.
Je Laime FAQ
Do the two halves of a Je l'aime trial pair contain the same product?
No. The pair contains shampoo and hair treatment. Keep each label and any production marking associated with the correct half.
Is Je l'aime Layered Hair Shine Booster Oil a leave-in oil?
No. This 60 mL product is a rinse-out hair treatment. Do not infer the application method from the word “oil”; follow the directions for Hair Shine Booster Oil specifically.

Before you rely on the decoded date
- For Layered, distinguish the 460 mL bottle from the 340 mL refill and the 10 mL + 10 mL trial pair. Check the actual bottle, pouch or each half of the trial pack rather than transferring a mark between formats.
- Record Extra Damage Care or Smooth Straight Care together with shampoo or treatment. Similar bottles and shared fragrance descriptions do not establish the same formula or manufacturing batch.
Common lookup mistakes
- Before pouring in a refill, photograph its mark and keep it with the refill date. The old bottle's original code continues to identify its first contents, not every later refill.
- Keep product-family names such as iP and Layered out of the lot input. They are range identifiers, not manufacturing codes.
