NON REMY HAIR:
This is basically the fallen hair which is collected from brushes, households and salons; hence the cuticles are mixed up (not in same direction). This hair must be chemically treated before we use it to make extensions and wigs.
This is the human hair which is chemically treated. During the production of hair extensions, the hair is soaked in acid to strip off cuticle layer which alters all the natural characteristics of hair strands.
