When you are using natural chemical-free henna, there is no instant dark henna stain after 30 mins of application. Natural henna requires some patience and proper aftercare.
Henna comes from a part of the world that is hot and humid, not air conditioned. AC is dry air and that dries out the henna and doesn’t promote dye-release. So, If you don’t have the luxury of a hot or humid day, as we do in South Florida, it’s even more important to seal and wrap the henna.
Using any of the above methods or simply sunbathing will do the trick. Wrapping the henna over night is the easiest, then just wake up and scrape the henna off in the morning! It will be a bright orange at first but within 24-36 hours the color will continue to develop resulting in a rich dark henna stain.
