Where is a Blauné kit code worth checking?
Check both carton flaps, the colorant tube crimp and the developer bottle base.
Check Blaune Cosmetic Batch Code
Kao's Japanese Blauné range is dedicated to gray-hair color and includes foam color, Lumiést, one-push and cream color, hair manicure, root color, mascara and color treatment. Some are two-part oxidative kits; others are temporary or treatment formats, so their components must be distinguished before reading a code.
Blaune FAQ
Is the printed shade number the lot?
No. It identifies the hair-color shade.
Do all Blauné products need mixing?
No. Hair mascara and some treatments differ from two-part oxidative color kits.
Blauné marks across gray-color kits, tubes and applicators
Before you rely on the decoded date
- For a color kit, inspect the carton flaps, colorant tube crimp, developer bottle base and applicator body separately. For mascara or root products check the container base; for treatment jars and tubes check the bottom or sealed end.
- Shade numbers, color names, agent 1/agent 2 labels, usage time, quasi-drug wording, barcode and Kao item number describe the product or step and are not manufacturing dates.
Common lookup mistakes
- Keep all kit components beside the outer carton and label each photographed mark by component.
- Never mix products from different shade numbers or kits merely because their codes look similar.
