Virgin hair typically refers to hair that has not been chemically processed or treated with any kind of hair products, such as dyes, perms, or relaxers. It is often considered to be the purest form of human hair, as it has not been altered in any way. Virgin hair is typically sourced from donors who have not undergone any chemical treatments, and the hair is collected in a way that preserves the cuticle and ensures that all of the hairs are facing the same direction. This helps to prevent tangling and ensures that the hair looks and feels natural.
