Virgin hair is completely natural human hair which has never been treated or had any chemical process carried out at the time of collection such as perm, dye, and colour. The donors of virgin hair must have long, healthy, and full hair. Virgin hair lasts longer and is much less likely to tangle than remy hair. Remy hair is very popular because it creates a natural look when worn. The best quality of remy's hair makes all the stratum corneum intact, which means they can be properly aligned to make them look completely natural. Remy hair is usually deeply cleaned and conditioned to restore shine and remove any impurities. The best thing about them is that they do not contain any harmful chemicals and are hypoallergenic.
