When human hair for white women is harvested from the donors and collated, chemical process is necessary for obtaining other hair colors apart from the original black, brown or blonde hair color. When this happens, the outcome is known as processed human hair. Also, since most human hair units come originally straight, there is need to process the hair in order to obtain variety of textures such as wavy, curly, kinky and afro textures.

The Remi Hair that remains in its original state without any form of alteration is known as unprocessed human lace wigs with silk top. These ones are pricier than the processed human hair units. They are often known as virgin human hair wigs.

Single Donor Human Hair

This simply implies that the hair was harvested from just one person. So, all the features in terms of hair color, cuticle alignment and hair texture would be uniform. The single donor human hair wigs are expensive as well.
