Real People, Real Henna: "Sarah C."
Sarah's hair after henna
Here is how I did my hair:
First I mixed 1 cup mildly acidic liquid with about 75 grams of Ancient Sunrise henna. I left it to sit overnight.
My boyfriend applied about half of it to my short hair, with surprisingly little mess. I covered it in plastic and put a hair towel around my head. I left it on for around six hours, I was too impatient to leave it on for longer and we wanted to go out to a movie. Unfortunately it didn't quite get as dark as I would have liked it, so the next day I used the rest of the mix that I had put in the freezer and left it on my hair for another six hours. After it was red enough to my liking, I mixed up some indigo with water and used it to dye the tips and the back of my hair. I left it on for about an hour.
This was very messy and dripped since I couldn't really wrap it up or it would ruin the design. It also dried out a little and didn't dye as well, (it was green at first), so I also had to do the indigo twice. In retrospect, it probably would have been easier if I had used tin foil to seal the ends up and there wouldn't be blue spots on the bathroom floor! But after a few mistakes, it finally came out how I wanted it.
