Double drawn human hair

Double drawn hair undergoes a manual process where shorter hairs are removed, ensuring that the majority of the strands (usually 80-90%) are the same length from top to bottom. This results in thick, full ends and a more voluminous appearance, whereas single drawn hair is tapered and thinner at the tips.

Buyers should verify the cuticle alignment (Remi/Remy hair) to prevent tangling and matting. Key metrics include gram weight per bundle (typically 100g), ratio of long hairs (e.g., 7-draw or 8-draw), and chemical processing levels. Ensure the hair can withstand bleaching to #613 or high-heat styling without significant degradation.

It is critical to ensure suppliers adhere to ethical sourcing practices. Look for certifications or documentation proving the hair is voluntarily donated or ethically traded. For chemical safety, products should comply with REACH (EU) or US FDA standards regarding the dyes and silicones used during the finishing process.

Request a burn test report (human hair turns to ash and smells like burning protein, while synthetic melts into a hard bead). Additionally, check for microscopic cuticle scales through third-party inspection. Professional sourcing via Made-in-China.com allows you to filter for Audited Suppliers who provide verified lab test results.

Always request a pre-production sample and a 'golden sample' for comparison. Use Trade Messenger on Made-in-China.com to document all quality promises. For bulk orders, hire a third-party inspection service (like SGS or Intertek) to perform a random pull test and acidity test before the final balance is paid.

Focus on long-term volume commitments rather than one-off discounts. Negotiate based on the hair length ratio; for example, ask for a higher percentage of full-length hairs for the same price point. Also, request customized packaging or private labeling as a value-add rather than just a price reduction.

Human hair is often subject to veterinary or sanitary inspections in certain countries. Ensure the supplier provides a Fumigation Certificate and a clear Certificate of Origin. For urgent stock, use air express (DHL/FedEx), but for large wholesale orders, sea freight is more economical if you manage lead times of 30-45 days.

Utilize Secured Payment services provided by platforms like Made-in-China.com, which hold funds in escrow until you confirm receipt of goods. Avoid direct wire transfers to private accounts; always ensure the beneficiary name matches the company name on the business license.
