Do i add creme developer with hair colour cream?

don%26#039;t wanna sound silly, its been a while since ive used it. I bought a Hair Colour Cream (with ammonia) and am not sure if I should add some Creme developer 40 vol with it?|||If it is permanent color, Yes, you need developing lotion or creme to %26#039;Activate%26#039; the color - However, your avatar has brown hair. If you are NOT going 3-4 Levels LIGHTER (From Brown To Blonde) you do not need 40 Vol. 20 Volume should be plenty 10 Vol. if you are going to the same level or darker.





Hope This Helps.





Good-Luck!|||Don%26#039;t add 40 volume...Only use that when your Bleaching(Lifting.) Black hair.......Use 20 or 10 volume...But, Yes, You almost always have to use Developer.
