Specially developed for oily, color-treated hair, this formula uses optimal color-protecting ingredients and ideal pH levels to repair post-color damage. It seals cuticles and forms a strengthening film on the hair surface, providing comprehensive color retention from the cortex to the cuticle for long-lasting shine and vibrancy.

[For Oily Scalps – Refreshing Volume] Designed for oily, color-treated hair, it gently removes excess sebum. Vitamin B6 regulates oil production, while volumizing agents keep hair fresh and full.

[Small Molecules – Deep Repair] Patented creatine and certified hydrolyzed wheat protein have small molecules that penetrate the hair core to strengthen and repair color-damaged hair, restoring healthy shine.

[Cuticle Sealing – Color Stability] The color-protecting formula with an optimized pH perfectly seals the cuticles. Amino acid-based chelating agents capture metal ions, reduce free radicals, and slow color fading.

[Large Molecule Film – Net-Like Coverage] The large-molecule color-locking technology forms a dense, net-like structure on the hair surface, thoroughly sealing gaps to minimize color loss and prolong vibrancy.

Quality Control System for Raw Materials, Semi-finished, and Finished Products :

• Raw Materials: Raw materials are sourced from qualified suppliers based on technical specifications and acceptance criteria. Procurement may request supplier questionnaires or QC audits. Upon receipt, staff check documents and packaging. Defective materials are quarantined. All materials are labeled with status, product name, supplier, date, and batch. QC inspects per standards and COA, outsourcing tests if needed. Only compliant materials are released and labeled; storage follows COA.

• Semi-finished Products: Production stages are documented. Before manufacturing, QC prints and authorizes batch sheets. Production follows procedures, formulas, and material lists with batch numbers. Each batch receives a unique number for traceability. QC conducts sampling; deviations are investigated and documented. Semi-finished goods are stored in proper containers and areas, with defined storage periods.

• Finished Products: Finished goods must pass QC inspection before release, with results recorded. Only products passing checks are released. Storage is managed by product needs and separated from nonconforming items. Returns are clearly labeled, stored separately, and evaluated by QC for further action. All products under review are clearly marked to prevent misuse.

The finished product has been tested and is free from the six major heavy metals, estrogen, silicones, plasticizers, nonylphenol, parabens, artificial colorants, formaldehyde, 1,4-dioxane, and microorganisms.

• Quality Inspection The QC team defines inspection methods and acceptance criteria for all products, including raw materials, semi-finished, and finished goods. QC supervisors review all results for approval. Sampling methods, frequency, and quantities are specified, with measures to prevent contamination.

• Raw Material Inspection: QC checks incoming materials based on the COA, SDS, or packaging material standards. Results are recorded for traceability. Qualified materials are labeled and stored; non-conforming ones are labeled, isolated, and staff and suppliers are notified. After re-inspection, compliant materials are released; others are returned or replaced, ensuring only qualified materials are used.

• Semi-Finished Product Inspection: Semi-finished products are moved to temporary storage and labeled for inspection. QC checks them against R&D specifications. Qualified products are released for filling or packaging; non-conforming ones are labeled and isolated. QC supervisors re-check quality before the next stage.

• Final Product Sampling: QC randomly samples 5% of finished goods at the end of packaging, checking appearance, batch numbers, and quantity. Before release, quality procedures must be followed. If any issues are found, an “Abnormal Report” is issued, causes explained, and corrective actions are taken. Records are kept for quality improvement and traceability.

Effectively Delays Color Fading Bleached and dyed human hair samples were repeatedly washed, rinsed, and blow-dried 25 times with the competitor’s product, Dr’s Formula Color Fixing & Scalp Treatment Shampoo (1st Generation), and Dr’s Formula Color Fixing & Scalp Treatment Shampoo (Refreshing & Weightless, 2nd Generation). The color retention was compared with a control group. Results confirmed that the 2nd Generation Dr’s Formula Color Fixing & Scalp Treatment Shampoo (Refreshing & Weightless) provided better color protection than the competitor’s product.
