So what does Remy Human Hair mean? Remy Hair is considered to be the finest quality of human hair because the cuticles are kept intact and not stripped, like in most other non-Remy hair extensions. Preserving the hairs’ cuticles and aligning them in a unidirectional fashion creates extensions that are completely natural in appearance. This process ensures that the hair remains super soft, shiny, silky and completely tangle-free throughout its lifetime.
