For people looking at deepening the natural colour of their hairs to black, the black coloured henna is the ideal choice. It can be used for either darkening the natural black colour of the hair or for people who have dark brown hair and want to acquire the natural black colour for the hair. Using accurate proportions of the indigo leaves along with the henna leaves and bark is what makes this powerful and natural dark colour. Even though the initial colour of the henna like natural henna may seem green, due to the mixture of the bark and the indigo leaves, the colour on application imparts the dark black colour to the hair, covering the greys. However, please keep in mind that this cover is powerful and can even hide the highlights or any other colour previously imparted to the hair. Due to this feature, in case there is any wrong colour that has been applied to the hair, it can be covered using this black coloured henna.
