HENNA

*Buy the freshest henna powder you can afford.

* Henna loses potency over time, so when the powder has lightened and turned brown, it won't leave a good stain. Look for brownish-green dark henna. Bright green henna may have dye added, to make it look fresh. The best hennas are pre-sifted, cheaper hennas may need to be sifted for body art. Store leftover powder in the freezer, where it will stay potent for at least a year.

*Measure out henna powder into mixing bowl. For body art, use a teaspoon for a few small designs, several tablespoons for ten to fifty designs. For hair, use about 100g for chin length, or 200g for curly shoulder length. You can use freeze leftover paste for a few months, so don't worry if you make too much.
*Add your sour liquid(lemon, sour curd ect...) while stirring. You want a consistency shoid be little thick, where the paste holds on the spoon and barely drips.

*Add the liquid a small amount at a time so it doesn't get too runny. Make sure you smash all lumps that form. For hair, add more liquid, or add water. It's easier to get into hair when it's thinner. For body art, it needs to hold together.

*Add your sugar. Like the liquid, add it slowly, until you get a nice, stringy texture. It's perfect if you can draw it out into long lines without breaking. If you want, you can add the sugar first, then liquid, or both at once. Experiment to see what works best for you. If your paste is for hair, skip this step.

*Add your essential oils. For sensitive skin, use lavender only or skip this step. Add about 1-3 drop per tablespoon of oil. You can use any oil that's skin safe, but only oils containing terpinols will darken henna (and eucalyptus isn't one of these.) The above list are some of the best, although there are others that may help darken henna. At this step, your paste should be smooth and thick.

*Cover the bowl with plastic wrap, foil, or a lid. Set it in a warm place, and wait. Henna needs from 4 to 24 hours to release its dye. Check the henna every few hours. When a brown crust is on top, the henna is near its peak. When you see drops or puddles of dye, the henna is at or passing its peak. If the paste has become dark brown throughout, it's probably degraded and will not stain well. Timing henna takes practice, low pH and heat speeds up the process. If you need it to be fast, try leaving it on a warm coffee pot. To slow it down, put it outside on a cold night.

*Use or store the henna when it's ready. You can either store it in sealable bags and freeze, or use it immediately. If the past seems too thick, thin it before using freezing. If it's for body art, you may want to strain it to make sure it's lump free. For hair coloring, you can now add conditioner, olive oil, eggs whites, yogurt, or any other product you like.
