| 1 | Assess the Formula Architecture | Check whether the formula has a clear functional structure, including cleansing agents, conditioning ingredients, humectants, emollients, preservatives, and pH-adjusting agents where appropriate. | Ingredients are listed using standardized cosmetic ingredient names, generally in descending order of predominance for ingredients above 1% under common labeling rules. | Vague “proprietary blend” language, missing ingredient categories, or strong performance claims unsupported by formula details. | Request the complete INCI ingredient list, product specification, target hair type, and intended use level. |
| 2 | Review Safety and Regulatory Readiness | Confirm that the product has a documented safety assessment and is intended for the markets where it will be sold. | A safety file should address ingredient restrictions, exposure, intended use, warnings, packaging, and microbiological quality. Requirements differ by jurisdiction. | No responsible safety contact, incomplete warnings, or claims that one certificate automatically covers every country. | Identify the target markets and ask for market-specific compliance documentation before production. |
| 3 | Evaluate Preservative and Microbiological Control | Pay particular attention to water-based shampoos, conditioners, masks, and styling products, which can support microbial growth if inadequately preserved. | Look for documented preservative selection, finished-product microbiological testing, and a preservative efficacy or challenge test when relevant to the formula. | “Preservative-free” positioning without an alternative microbial-control strategy, unexplained odor or color changes, or missing batch-release criteria. | Request recent microbiological results, stability data, and the product’s recommended storage conditions. |
| 4 | Check pH and Scalp Compatibility | Verify that the finished product’s pH is appropriate for its product type and intended scalp or hair application. | The specification should state a measurable pH range and the test method. Product suitability depends on formulation, use pattern, and local regulatory requirements. | No pH specification, inconsistent pH between batches, or claims that a single pH value is ideal for every hair and scalp condition. | Test retained samples with a calibrated pH meter or review independent laboratory results. |
| 5 | Demand Full Ingredient Transparency | Ensure that all intentionally added ingredients, fragrance components where disclosure is required, colorants, and relevant allergens are properly documented. | The label should use recognized ingredient nomenclature and comply with the disclosure rules of the selling market. Fragrance-allergen requirements vary by jurisdiction. | “Natural” or “clean” claims used instead of a complete ingredient list, undisclosed colorants, or inconsistencies between the label and technical file. | Compare the artwork, INCI list, specification, safety documents, and final bulk formula line by line. |
| 6 | Verify Stability and Packaging Compatibility | Confirm that the formula remains acceptable throughout its expected shelf life and does not interact adversely with the container or closure. | Stability programs commonly monitor appearance, odor, color, viscosity, pH, microbiological quality, and packaging performance under defined conditions. | Only a short room-temperature observation, no packaging compatibility review, leakage, separation, fading, or pump failure. | Approve a production-representative sample in the final packaging before confirming a large order. |
| 7 | Separate Performance Claims from Marketing Language | Select products whose claims can be supported by objective testing, such as combability, breakage reduction, cleansing performance, or consumer-use evaluations. | Claims should be truthful, not misleading, and appropriate for cosmetics. “Repairs” or “treats” claims may create regulatory issues when they imply a medical or permanent structural effect. | Guaranteed hair growth, permanent repair, cure claims, or dramatic before-and-after statements without a defined test method. | Ask for the claim-substantiation protocol, sample size, test conditions, results, and limitations before using the claim on packaging. |
