Remi hair, which is more commonly spelled "Remy hair," is the highest quality of human hair available for human hair weave & extensions. The biggest characteristic of Remy hair is that the cuticles are kept intact. This means that all the roots are at one end of the weft, and all the tips are at the other. Keeping the cuticles in the same direction not only replicates the natural growth of hair, but also prevents tangling. In non-Remy hair, tangling and frizz are common, because the cuticles rub against each other. The sleek look of Remy hair is part of what makes it so desired, expensive and natural-looking.
