Remy hair extensions are of the finest quality hair extensions, unlike non-remy hair. The hair length of each and every hair is exactly the same. This hair is carefully stored after collecting it from a specific donor. These hair extensions are of a high quality and can possibly be treated chemically to ensure a very fine quality. Remy hair extensions are tangle-free since they are of the same length. The reason why remy hair extensions are stored is because the cuticles stay fresh and healthy.
