Bigen FAQ
Should I treat the shade name or number or the colorant and developer labels as the Bigen lot code?
No. The Bigen lot is the separate compact mark tied to production, not that product-label information.
Bigen — Is one date enough for every item in a set?
Not necessarily. Check the production and expiry marks on every item separately.
Bigen hair color lot and date guide
Before you rely on the decoded date
- On Bigen products, inspect the sachet seal, the bottle base and rear-label edge, the tube crimp, the carton flap. Record whether each mark came from the product or the box; that location is useful when comparing them.
- Use the short Bigen production mark rather than the shade name or number or the colorant and developer labels. That information describes the product or its regulated labeling.
Common lookup mistakes
- Photograph the complete Bigen mark in daylight before discarding the carton; faint ink, embossing, and punctuation can change the reading.
- Use the decoded date as one Bigen hair color clue, then also check the printed expiry or PAO symbol, storage history, seal, texture, and odor.
What to check next for Bigen
