Is it true that hair can turn greenish when coloured with herbal hair dyes?Updated a month ago

With some colors, especially dark or cool shades, a slight greenish tint after rinsing is not unusual. Since plant-based hair dye continues to develop for 48 hours after rinsing, this will disappear on its own, and the correct shade and coverage of the color will become apparent.

To ensure that the green hue disappears completely on its own, pay attention to the correct mixing temperature, application time, water bath, pre-pigmentation with ColorPrep if necessary, and also to covering the color with a warm towel while it is taking effect.
