Hair rebonding

When sourcing rebonding kits, you must verify the concentration of Ammonium Thioglycolate (ATG), which is the primary reducing agent. For sensitive or damaged hair, look for Cysteamine-based formulas as they are gentler. Additionally, ensure the presence of conditioning agents like Keratin, Argan Oil, or Collagen to mitigate structural damage during the chemical process. Always request a Material Safety Data Sheet (MSDS) to confirm the pH levels, which should typically range between 9.0 and 9.5 for the relaxer.

Compliance is non-negotiable for cosmetic imports. Ensure the supplier meets ISO 22716 (GMP for Cosmetics) standards. For the US market, products must adhere to FDA VCRP regulations; for the EU, they must be compliant with Regulation (EC) No 1223/2009. Specifically, check for the absence of prohibited substances like Formaldehyde or excessive levels of heavy metals, verified through COA (Certificate of Analysis) reports for every batch.

Professional suppliers offer tiered formulas. 'Strong' variants have higher alkaline content for resistant, virgin, or coarse hair. 'Normal' variants are balanced for medium-textured hair, while 'Damaged/Sensitized' variants contain lower chemical concentrations and higher protein protection for previously treated hair. Sourcing a multi-step system (Relaxer + Neutralizer + Post-Treatment Mask) is essential for professional salon results.

The neutralizer (usually containing Hydrogen Peroxide or Sodium Bromate) is critical for re-bonding the hair's disulfide bonds. Ensure the supplier provides a neutralizer that is viscosity-matched to the cream to prevent dripping. The concentration of Hydrogen Peroxide should typically be around 2% to 3% to ensure effective oxidation without causing unnecessary color lift or dryness.

Hair rebonding products are classified as liquid chemicals, which may be flagged as 'sensitive goods' by carriers. You must ensure the supplier provides UN-rated packaging to prevent leakage under pressure changes during air freight. For sea freight, ensure the containers are temperature-controlled or stored away from heat sources to prevent the chemicals from destabilizing or the tubes from bloating.

Prioritize 'Audited Suppliers' on Made-in-China.com who have undergone on-site inspections by third parties like SGS or Intertek. Check their 'Business Type' to ensure they are a manufacturer rather than a trading company, which allows for better control over formula customization (OEM/ODM) and ensures consistent batch quality.

Since chemical efficacy varies by hair type, always request a 500ml sample for salon testing before a bulk order. Negotiate a tiered MOQ where the initial order can be smaller (e.g., 500-1000 sets) to test market response. Ask for volume-based discounts, typically ranging from 10-20% for orders exceeding 5,000 units, and clarify if the price includes customized private label printing.

Use Secured Payment terms offered through the platform to protect your funds until shipping documents are uploaded. To ensure quality, hire a third-party inspector to perform a 'During Production Check' (DUPRO) to verify that the viscosity, scent, and pH levels of the mass production match the approved pre-production sample.
