Can I place FRAMCOLOR Eclectic under heat for longer-lasting color results?

Do I need to process FRAMCOLOR Eclectic under heat?

It is not necessary to process FRAMCOLOR Eclectic under heat for longer-lasting results.  The unique formulation with the Encapsulation Technology results in the longest lasting demi-permanent system in the industry when processed at room temperature.  Heat is only recommended when processing very resistant gray hair.
