Review (4/5): Asian black hair need a few applications
I like this product for its gentleness on the hair. I started with natural Asian hair (albeit has some brow/red tones under natural light). It took me 3 applications (3x product over course of 6 months) to get to a medium brown where I'm happy and other coloring will likely come through. The first application my mom didn't even say anything so it must have been a very slight change. The result looks more evident under natural light.
The instructions are easy and helpful. I tend to leave mine on for 45 minutes but I'm not willing to keep it longer because while it is gentle it'll still srip something from the hair strands.
My hair is thick as in the stands and the volume so that likely impacted how much the product worked. I'm happy with my third application result and look forward to using other foam coloring soon.
