When hair extensions are processed, they tend to have a shiny coating due to the silicone used during chemical processing. This makes the human Hair left out that is free of silicone, very visible and difficult to blend. When extensions are are truly in their Purest, Raw form, they will blend perfectly with your own hair. Leave Processed Extensions in the past, & purchase Pure Virgin Extensions that last!! ***a heat protectant is always recommended when applying heat to human hair.
