And color unevenness does not occur in the finish. Since it can be applied easily, skills such as blocking and mirroring are not required, and the time required for hair dyeing is much shorter than before. In this way, it has far superior performance as compared with the conventional one, so it is being supported by a wide range of customers regardless of gender and age group.
