If you are curious about DIY home-hair coloring, I highly recommend using DIY hair color by Madison Reed, which Resorcinol-Free.

If you purchase a Madison Reed Radiant Color Kit, you will receive not only the colors of hair colors your choice, but also the necessary tools to apply it. The entire line is designed for the DIY hair colorer! And if you need to tone in between coloring, be sure to check out their Color Reviving Gloss to refresh and revive your hair.

Also, I recommend a shopping stop at Beauty Store Depot for all your other DIY hair cutting and coloring tools to fill your toolkit!
