Wholesale keratin hair treatment

The most critical factor is the Formaldehyde content. Professional buyers must distinguish between 'Formaldehyde-free' and 'Low-formaldehyde' formulas. Ensure the product complies with EU Cosmetics Regulation (EC) No 1223/2009 or US FDA guidelines, which typically limit formaldehyde to less than 0.2%. Look for alternative active ingredients like Glyoxylic Acid or Cysteine for safer, non-toxic smoothing results.

Performance is measured by the longevity of the treatment (typically 3–5 months) and the reduction in frizz. Request the supplier to provide before-and-after laboratory test results on different hair types (Type 1 to Type 4). High-quality treatments should include hydrolyzed keratin proteins with low molecular weight for deeper cuticle penetration and Argan or Jojoba oils for added shine and thermal protection.

A complete wholesale kit should include a Clarifying Shampoo (pH 8.0-9.0) to open cuticles, the Keratin Treatment (pH 3.0-4.5) to seal the hair, and a Sulfate-free After-care Mask. Ensure the packaging uses air-tight induction sealing to prevent oxidation and maintain the stability of the active proteins during long-term storage.

Prioritize manufacturers with GMPC (Good Manufacturing Practice for Cosmetics) and ISO 22716 certifications. These ensure the production environment meets international hygiene and quality control standards. Additionally, request a Material Safety Data Sheet (MSDS) and a COA (Certificate of Analysis) for every production batch to guarantee chemical consistency.

Always request a paid sample before placing a bulk order and conduct a 'strand test' to verify efficacy. Use Made-in-China.com's Secured Trading services to ensure payment is only released after the goods pass quality inspection. Avoid suppliers who cannot provide traceable raw material sourcing documentation.

Keratin treatments are liquids and may be classified as 'Sensitive Goods' or 'Dangerous Goods' if they contain flammable alcohols. Ensure the supplier provides a UN38.3 report or a Non-Hazardous Goods Declaration for air freight. For sea freight, use FCL (Full Container Load) if possible to avoid cross-contamination with other goods in LCL shipments.

Standard MOQs for custom branding usually range from 500 to 1,000 units. Negotiate a tiered pricing structure where the unit price drops by 15-20% as volume increases. Ask for 'Value-Added Services' such as free label design or customized fragrance options (e.g., chocolate, grape, or mint) to differentiate your brand in the local market.

For the US, ensure the manufacturer is FDA registered and the labels comply with VCRP (Voluntary Cosmetic Registration Program) requirements. For the EU, you must have a Responsible Person (RP) and register the product on the CPNP (Cosmetic Product Notification Portal). Failure to provide these will result in customs seizure and destruction of the shipment.
