Mixing henna for use on hair, there are many options. Many ingredients may be added for the benefit of their conditioning, color enhancing and aromatic properties. These include but are not limited to:
Cinnamon, for enhancing brown tones and leaving your hair smelling like spice cake.
Coffee, for darkening & neutralizing gray.
Black tea, for deepening the color.
Jojoba, Walnut, Olive, Amla oil for conditioning.
Rosemary oil for conditioning and stimulating hair growth.
Beet juice, for dark purple and reds.
Red wine for red tones.
Cloves for dark reds & spice cake hair.
Chamomile & Turmeric for golden highlights (with neutral henna only)

Other options are:
Eggs, for protein & conditioning properties. It is important to note that eggs lessen the intensity of the color. I suggest a few tablespoons of your favorite non-coloring conditioner as a substitute.
Lemon juice as the basic liquid for mixing. The acidity of the lemon juice makes the henna paste “take” well to your hair.

I recommend this source of henna powder because I have used it many times and I’m aware of its quality. Because your hair is important, it is always better to choose a reliable source of natural henna. Many products on the market that I have tested were not 100% natural henna powder.
