Are Proqualite agent 1 and agent 2 batch codes?
No. They identify the two ordered treatment stages. Keep those stage labels separate from manufacturing marks.
Proqualite Hair-Straightening Lots | Utena Kit Components
Proqualite is Utena's hair-care and straightening range. Its chemical straightening set has first and second agents plus follow-up care; daily shampoo, treatment and styling products are separate products, not substitutes for kit components.
Proqualite FAQ
Can a long-hair Proqualite box date a loose short-kit tube?
No. Preserve the exact kit version and its own components; similarity in branding does not establish a shared production record.
Does Proqualite daily care follow the straightening-set instructions?
No. Match the full product name before use. Shampoo, leave-in styling care and chemical straightening kits are different product types.

Before you rely on the decoded date
- Keep the first agent, second agent, Hot Iron Manicure and Smooth Keep Essence with their original kit. Record marks from each container or sachet independently instead of treating the four-step system as one code.
- Short/partial-hair and long-hair kits differ in the quantities of the first and second agents. The numbers 1 and 2 indicate application order, and gram amounts indicate quantity, not production time.
Common lookup mistakes
- Utena requires a preliminary test on part of the hair before each use of the straightening set. Do not replace that test with a favorable batch-date result.
- Retain the kit leaflet. Daily leave-in hair care and the chemical straightening agents have different instructions, even though both carry the Proqualite name.
