Whether you want pure and natural cassia, henna, indigo we have it ready for you. Use your favorite way to mix henna. Not sure how to mix and apply straight henna powder? I'd suggest you start with the self mix dye, which gives just as strong a color and is far easier-and doesn't drip. You can perm, chemical color or bleach over this henna, of course do a strand test to be sure of your color results. There are no harmful metallic salts. Ingredients: Henna (lawsonia inermis) or cassia (cassia obovata) or indigo (indigoferra tinctoria). 100 gm, 1 cup volume should do average chin length hair.
