Mix Black henna powder and water

Stir until smooth
Pick the stirring stick or disposable spoon and blend the black henna mixture until it form a lightly thick but smooth hair paste. Make sure that the paste is neither too thick nor too watery. So adjust the paste by adding in more henna powder or water.

Now divide your hair into sections. Dip the hair brush or a large spare toothbrush into the black henna hair past and start apply it from the roots of the hair to the tips.
Rinse off the black henna hair paste
Once you apply the black henna hair paste, leave it for some time until you attain the desired black color. Rinse off the Black Henna Paste with lukewarm water and wipe your hair dry. Enjoy the silky black hair!
