First, let’s start with the definition of cold pigment dyeing of hair. What is cold pigment dyeing? General speaking, it refers to any hair dyeing using pickling dye with no requirement for hot temperature during the whole process of dyeing.
The major working principle of cold pigment dyeing is to attach the pigment to the surface of the hair, which differs from the penetration of neutral dye.
Similar with most of hair coloring ointment, cold pigment dyeing means to paint the hair with color to prevent the loss of the original pigment of the hair. Therefore, it is hard to bleach the hair right after the cold dyeing process. It is easy for the hair to get color on with cold dyeing, meanwhile, the color on the surface of the hair is easy to fade as well.
In conclusion, If you would like to further preserve the original nature of good hair, it is not suggested to cold dye it. We normally do not apply cold dyeing onto the hair with excellent quality. In other words, if you did find some problems occurring to the hair which has been cold dyed, it probably because the hair originally doesn’t really have very good quality itself.
