Addcolo Hair extensions are real remy human clip-in hair extensions. Remy hair is considered to be the highest grade of human hair extensions because the cuticles are kept intact, which prevents tangling and substantially prolongs product lifespan. Preserving the hair cuticles and aligning them in a unidirectional fashion creates extensions that are completely natural in appearance. The hair is meticulously sorted to select only the finest strands of desired length. This process ensures that the hair remains ultra soft, shiny, silky and tangle-free throughout its lifetime.
