Polishing is to wrap a thin layer of polymers outside the hair (products originating from Korea) to make hair look shiny and softer.

To get the best hair color, we have to lighten the hair by raising the foundation or bleaching the hair before dyeing, then adding shade.
The process of glossing over hair is almost non-oxidized as they are extracted from a predominantly silicon component. This layer of silicon only attaches to the shell of the hair, not to the body of the hair, and sticks to the hair like a layer of COLOR PAINTING, making the hair hard, losing the softness, almost like nail polish of girls. . The process of getting color on the scalp is quite difficult to remove the color. Therefore, when you want to dye to a different color, the bleaching will certainly affect and damage your hair.
However, the hair removal also has some difficulties because it can not completely remove red, blue, purple from your hair. So the process of converting to other hair colors is quite difficult and can cause damage as well as abrasive structure, broken hair links. If your hair is too damaged and you want to have healthy, shiny hair in a split second, you can try the exclusive nano varnish dyeing technology at Zema. This technology will help minimize the side effects of shade on your hair.
