Can we test the shade before hair coloring?
You should definitely check the swatches of hair colors before getting all the hair colored.
One easy way to check the hair color swatches online, the picture shows an indicate shade of the color (but the actual shade depends on the texture and the base color of your natural hair)
So the best way is to color a strand of hair that is not too visible and check if you love the shade.
