Revlon Professionals’ Revlonissimo Pure Colors 0.22 Hair Dye allows you to neutralize the client’s hair color in order to ensure that their hair fiber remains healthy. This hair dye allows customizing a base color making it bolder or more natural, depending on the client’s choice. In turn, this hair dye has the function of neutralizing common undertones present in hair dyes, thus making it more neutral, whether natural or daring without darkening.
