I currently process my color under heat for 5 minutes because of very resistant gray coverage. Should I process FRAMCOLOR 2001 INTENSE under heat also?

If you are currently processing 5 minutes under heat because of resistant hair, you can also process FRAMCOLOR 2001 INTENSE under heat for 5 minutes, still reducing the total processing time in half.
