Our company has three qualities of hair, Raw hair, Super virgin hair and Top virgin hair. We only provide the absolute best 100% unprocessed human hair without any type of chemical treatment. The main difference the hair types is Raw hair is hair from the same person (100% cuticle aligned) , Super virgin is hair from one or two people mixed together (90-95% cuticle aligned), and Top virgin is hair from two or three people mixed together (80% cuticle aligned). Because everyone's hair scales are different, like super virgin and top virgin are a mix of multiple people's hair, so the bleaching and coloring will be uneven, and there will be varying degrees of color difference. Under a microscope, hair is scaly, like fish scales, the scales are the building blocks of the hair. Intact scales are smooth and undamaged with neat edges. With smooth scales, hair is smooth, shiny and easy to comb. Therefore, the presence or absence of intact scales affects the quality of the hair. So, because raw hair is from the same donor, it is the best quality!
