What is the difference between Grade A and B?

Grade A: hair is 100% natural, real hair selected to create a bundle of luxurious strands for a flip worthy experience. The hair is fuller, thicker and raw. Since it has not been processed, it gets better and lasts longer with every use. Lasts 2+ Years

Grade B: hair is slightly blended virgin hair strands to make a premium blend bundle. Grade B is processed and will expire over time. Because of processing, this hair has been stripped of its natural properties but still remains the most popular hair on the market. Lasts 1+Years

Grade C: hair we do not carry in our Studio but is important to mention. Grade C hair does circulate and tends to be extremely mixed virgin hair and can often be mislabeled as virgin hair when in truth, it is regular beauty supply hair or even synthetic. Not recommended
