Step 1: Directions to dye hair / grey hair: Mix 100 grams (for long hair) of Henna powder with 3 tablespoons of lemon juice or apple cider vinegar. Lemon juice or apple cider vinegar helps in releasing the dye in Henna. Add either yogurt, full-fat milk, warm strong black tea or warm strong black coffee a little by little to get a thick paste. Keep closed in an airtight container to retain moisture for 6 hours or ideally overnight. It is advisable to use a ceramic or a glass bowl for this mixture as it will not absorb any stains from the mixture. However, the mixture can be used within 2 hours if needed urgently.
Step 2: Additional information: After 6 hours, you could also add an egg to the mixture. The biotin in the egg helps to maintain healthy roots and follicles of the hair.
Application: Please use gloves to apply the paste. Apply a bit of oil around your forehead, ear and neck area around your hairline to protect your skin from any color that may transfer during the application. Apply the mixture from the root to the tip of your hair, strand by strand to get full coverage. Once you have applied the mixture to your hair, tie it securely into a bun at the top of your head depending on how long your hair is. Cover your hair with a shower cap or wrap it in cling film and leave for 2 to 4 hrs. After 2 to 4hrs wash off the mixture with lukewarm to cold water with a mild shampoo. Finally, rinse in cold water to close the hair follicles.
