Remy hair is hair that has been collected by a hair donor. The cuticles are not stripped and remain aligned in one direction. Most human hair sold in the hair extensions industry undergo a cuticle-stripping process called an acid-bath. Then, a silicone is placed over the cuticles to give the hair a faux shine and smooth appearance. This silicone wears off when the hair is washed, therefore, the cuticles are disturbed and return back to their unruly state, causing the hair to mat and tangle easily. Remy hair does not mat or tangle because all the cuticles are aligned and intact without the use of silicone.
Remy hair has a smoother, shinier, and healthier appearance than regular human hair. When washed, it will not mat and tangle. Virgin remy hair has not been chemically processed; this hair is raw and natural in other terms. Non-virgin remy hair underwent some sort of chemical processing in order to achieve another color.
An individual who uses remy hair extensions will experience less matting and tangling than an individual who uses regular human hair extensions. Remy hair also gives a more natural appearance than regular human hair extensions.
Remy hair is the most expensive type of hair to purchase in the world because of the special care needed to maintain it.
