Mix Henna with enough lemon juice in a non-metallic bowl (or any acidic liquid such as apple or orange juice) to make a thick paste (like extra thick set custard or yoghurt) cover with cling film and rest overnight to release dye. Will be lumpy but smooth after resting.2. Next day or after a few hours (3-4 if short of time) uncover and mix into smooth paste. Apply to hair (washed or unwashed) with cone or simply using fingertips which is far easier (make sure you have gloves on!)3. Start from the back of the neck upwards applying generously from roots to hair ends until hair completely covered.4. Wrap hair with plastic wrap and leave in for as long as you can but for at least 2 hours.5. Wash henna out with shampoo or rinse out thoroughly if you washed hair before applying. Finish hair off as normal OR, if using Indigo after Henna to achieve black hair, towel dry hair and apply indigo.6. Hair colour will get darker within 2-3 days.
