Extension brazilian hair

To ensure quality, perform a burn test: human hair turns to ash and smells like burning protein, while synthetic hair melts into a hard plastic bead. Additionally, check for cuticle alignment; high-quality 'Remy' Brazilian hair should have cuticles facing the same direction to prevent tangling and matting over time.

Focus on Hair Ratio (Single Drawn vs. Double Drawn). Double drawn hair has a higher percentage of long hairs, providing thickness from root to tip. You should also verify the weight per bundle (typically 100g ± 5g) and ensure the hair can withstand chemical processing such as bleaching to #613 blonde without significant degradation.

Suppliers should provide Health Certificates and Fumigation Certificates to ensure the organic material is free from pathogens. For the US and EU markets, ensure the dyes and processing chemicals used comply with REACH or California Proposition 65 to avoid skin irritation issues for the end consumer.

For B2B buyers, a mix of Machine Wefts (high volume), Tape-ins (fast application), and Pre-bonded Keratin tips (long-term wear) is recommended. Ensure the Italian Keratin glue is used for bonded extensions to provide a strong, residue-free hold that does not damage the natural hair.

The primary risk is 'Non-Remy' hair being sold as 'Remy', which leads to severe tangling after the first wash. Another risk is weight fraud, where suppliers include heavy rubber bands or moisture to meet weight requirements.

Request a tiered pricing structure based on length (e.g., 12" to 30"). For initial orders, negotiate a sample kit MOQ to test different textures (Straight, Body Wave, Deep Wave). Professional buyers can often secure a 5-10% discount by committing to a consistent monthly volume rather than one-off large purchases.

Due to the high value-to-weight ratio, Air Express (DHL, FedEx, or UPS) is the standard. It provides end-to-end tracking and typically arrives within 3-5 business days. Ensure the commercial invoice accurately reflects the HS Code 6704.20 (Human Hair) to avoid customs delays and ensure correct duty calculations.

Prioritize Audited Suppliers who have undergone on-site inspections by third-party agencies like SGS or Intertek. Review their Audit Reports specifically for their production capacity and quality control flow to ensure they can handle large-scale wholesale orders without compromising quality.
