Mix ½ cup (50 g) of Indigo Henna Powder with ¼ cup (59 ml) of warm water. Stir to combine. Once you’ve mixed the powder and water, cover the bowl with plastic and let it develop at room temperature for about 1 hour.
Apply this paste uniformly on hair with the help of brush.
Cover hair with plastic cap and leave it around 60 to 90 minutes as depends upon desired shade.
Rinse off hair with plain water.
Note: Hair must be washed and dried before application of Indigo-Henna.
