Remy hair 100% virgin hair that has come from one donor, with the cuticles in-tact and all hairs aligned in their natural growth pattern (all cuticles going in the same direction). The process is done by hand and it is a labour intensive process. This makes the extensions smooth and free of tangles. Many companies claim to have Remy hair, when the hair truly isn't. Remy hair is very hard to identify to the naked eye.
