There are a number of colors of henna dye. Some shades include blonde, brown, auburn and mahogany, but those may be mixed with other dyes such as indigo, rhubarb, and Lawsonia and are not truly henna dyes. Normal hair dyes that can be achieved with henna include strawberry blonde, red, auburn, brunette and black.
One mix used to create a soft red-brown tone is 100 grams of mehandi henna with 1/4 cup of red wine. A tablespoon of lemon juice should also be used. Water is then added to make the consistence of the mix similar to traditional dyes, which is slightly thinner than a paste. This mix is left on the head for approximately an hour after allowing it to develop in a dish or bottle for 3 hours.Learn more about Hair Color
