Human hair wig

B2B buyers must understand the hierarchy of hair quality to ensure product longevity. Virgin Remy Hair is the highest grade, where cuticles are intact and aligned in one direction, preventing tangling. Non-Remy hair often undergoes acid baths to strip cuticles, leading to a shorter lifespan. Always verify if the hair is 100% human hair or a human hair blend, as synthetic fibers will melt under high-heat styling tools.

The lace base determines the natural appearance and comfort. HD Lace (High Definition) is currently the market leader for its invisibility against all skin tones. Swiss Lace is durable yet soft, making it ideal for daily wear. Ensure the supplier uses hand-tied knots rather than machine-sewn ones for the frontal area, and check if the knots are pre-bleached to enhance the realistic 'scalp' look.

Since human hair is a biological product, it must undergo strict sanitization and fumigation processes. Request a Fumigation/Disinfection Certificate to ensure the goods clear customs without quarantine delays. Additionally, ensure the dyes used for coloring meet REACH (EU) or FDA (US) chemical safety standards to prevent scalp irritation for the end consumer.

Pricing is highly sensitive to density (standard is 150%, 180%, or 250%) and length (measured from crown to end). Be aware of the 'Double Drawn' vs. 'Single Drawn' distinction; double drawn hair has shorter hairs removed manually, resulting in thick ends, which commands a significant price premium compared to single drawn hair that thins out at the tips.

The most prevalent risk is material substitution, where suppliers mix animal hair (like yak) or synthetic fibers into '100% human hair' batches. To mitigate this, use Made-in-China.com's Secured Trading services and request a burn test video or a third-party inspection report from agencies like SGS or Intertek before final payment.

For customized textures (e.g., Kinky Curly, Deep Wave) or specific cap sizes, suppliers usually require a higher MOQ (typically 5-10 pieces per spec). Negotiate for sample kits at a discounted rate first. For long-term partnerships, aim for a tiered pricing model where the unit price drops by 10-15% once your cumulative monthly volume exceeds 100 units.

Human hair is sensitive to moisture and compression. Ensure the supplier uses anti-static silk bags and sturdy outer cartons to prevent the hair from losing its style or developing mold during sea freight. For high-value lace wigs, Air Express (DHL/FedEx) is recommended to reduce transit time, as lace can become brittle if exposed to extreme temperature fluctuations in shipping containers for too long.

Always conduct transactions through verified suppliers on Made-in-China.com who have undergone 'Audit Reports.' Utilize Escrow-based payment terms where funds are only released upon confirmation of receipt and quality check. Clearly define the Return & Refund Policy in the Proforma Invoice (PI), specifically addressing 'quality not as described' scenarios.
