We have our own sourcing team to get the hair from donor directly instead of getting them from trader. We pay attention to the refined process and we never use the acid during process. We bleaching our hair with water under 40 centigrades which can keep the cuticles intact to prevent tangling and prolong the lifespan of hair. The hair remains ultra soft,shiny, silky and tangle-free throughout its lifetime. Every single items pass through several rounds of strict quality inspections before they are sent to customers. We even consider the package for transportation safety. So take every aspects into consideration to ensure our quality.
