I have been user of nupur heena since 13 years. with different other ingredients but Nupur color is nice and unique it has launch now only. This includes coconut oil so may not use as heena. Using heena is different it takes about 2-3hrs to dry. but color takes 30 to 1 hrs to keep its not needed to dry what ever the color is it will be done in those hrs only. yes its really messy with the oily hair its better to shampoo with your regular shampoo. no worry color will remain same.
