You need to add 2T apple cider vinegar to the henna and coffee mixture. The best thing to do is to mix the vinegar and henna in a bowl, cover with plastic wrap and let it stand at least 8 hours. Then add brewed coffee to get the consistency you want. Apply to the hair and cover your head with plastic wrap and then put a beanie over it. Make sure you wait for at least 4 hours before rinsing your hair, and do not shampoo it for at least 48 hours. Just use conditioner to rinse the henna out. Also, don't be surprised if your grey hair still looks grey just after you apply henna. Henna will continue to oxidise and will grow darker in the next couple of days. Goodluck!
