    As the substitute of synthetic black hair coloring materials, we focused on benzopyran natural colorants as known as a pleochroism dyes which forms coordination complexes with metal ion. We selected sappan wood(brazilin) and logwood(hematoxyilin) to represent benzopyran-based colorants. Ferrous sulfate and the extract of alder tree or tannic acid were used for mordanting. Wool was applied as the reference for hair dyeing to improve the color properties. By using both of metallic- and bio-mordants, we obtained the dyed hair of deep black color and high color strength with less than 8% of the surface reflectance. Light colorfastness of the dyed hair was relatively good and the rating 4-5 was obtained up to 100 hrs. And the rating to washing of the dyed hair was maintained 5 up to 30 cycles for the evaluation of colorfastness.
