Where should I look on Lazartigue shampoo?
Check the bottle base and back label, then compare them with the carton or refill packaging if supplied.
Check Lazartigue Cosmetic Batch Code
Lazartigue sells shampoo and conditioner in bottles, repair and age-care masks in jars, concentrated serums and oils in smaller vessels, hair color kits, supplements and selected shampoo refills. Fortify, Repair, Ageless, Colour Protect and L'Huile des Rêves identify product lines rather than manufacturing dates.
Lazartigue FAQ
Is SPF50+ on Solar Protect a batch code?
No. It is the stated sun-protection level and not a manufacturing reference.
Can a Lazartigue refill use the bottle's code?
No. Read the pouch's own printed or sealed-edge mark because the refill and reusable bottle are separate packages.
Lazartigue marks across bottles, jars and refill pouches
Before you rely on the decoded date
- Inspect a bottle's base and back label, a mask jar's underside and rim, a serum bottle's bottom, and a refill pouch around its heat-sealed edges. For a boxed color kit, compare the outer carton with each component instead of assuming every number belongs to one batch.
- SPF50+, 230°C heat protection, shade numbers, millilitre sizes and supplement counts describe use or format. A useful production mark is normally a separate short printed, stamped or embossed string.
Common lookup mistakes
- Keep the carton or refill sleeve until you have photographed both it and the primary container; a mark may be clearer on only one surface.
- Do not transfer a date from a full-size bottle to a refill pouch or travel size merely because the formula name matches.
