There are many ways to mix up henna paste.  Dabble with recipes until you find something that really suits you and gives a consistent stain.  Different powders stain differently...but they all take a couple of days to darken completely after the paste is removed.

I spent a few years making the Hot Mix and while I still occasionally use it, I have found myself primarily using the lesser ingredient method for the last few years. 

quick and easiest recipe...
dump 100 grams of quality henna powder in mixing bowl
add about a 1/2 cup of lemon juice (give or take)
mix well (it will be lumpy and thick)
add 1/8 cup of sugar (give or take)
add essential oil** such as tea tree, eucalyptus, or lavender  (2-3 tbspn)
add hot distilled/purified water until I have the consistancy I need.
Mix until lumps are mostly out.  Then cover with plastic wrap and set in a
warm area waiting for the dye to release.  Once the dye has released then
mix one last time to beat all the lumps out.  Then you can bag this up into
smaller batches.  Use sandwich baggies or carrot bags and make sure the
air is out before sealing.  Then you can freeze them until you need to use it.


If you are doing events this is a great way to always be prepared (I double the recipe for 200g of powder).  If you are just doodling for a very occasional hobby then this amount of paste will last you a long time.
**I add "Magical Mehendi spice blend" which is a specfix mix of essential oils for stain and scent.

This is the formula that I previously loved to use when making my henna paste.
Everyone has different recipes, and while some elements of my recipe might
not be necessary it has become my ritual when making paste. Experiment
and find the right formula for yourself. It can be as easy or complex as you like.
                                                                                                                                          What you will need:
                                                                                                            * slice and dry (bake overnight in 200* oven) 3-4 limes
                                                       * good henna powder
                                              * black tea bags
                                           * 1/8 c. cloves
                                                                                              * 1 tbsp. sugar (Sucanet, jaggery, brown, raw)
                                                                                                       * 1 oz. eucaluptus essential oil (you won't use it all)
                                                                                                   * lemon juice (juice 1 lemon...you won't use it all)
                                                          * very fine mesh strainer
                                            * nylon stocking
                             * water

In a saucepan place 2 cups of water and bring to a slow boil. Add the dried limes, tea bags, cloves, and sugar. Stir then cover the saucepan and let cook for 30 minutes.
While the juice is cooking, place your henna powder in a bowl. Remember a little powder goes a long way. Add the eucalyptus oil, about a tsp. at time, and stir. It will be chunky, but work the oil into the powder. I like to just work in 1 or 2 tsp. of the oil to 'wet' the powder. Then take the lemon juice and add it a little to the chunky paste. Stir this again. Repeat this until the paste is a little looser, but still thicker than spackle. It should be somewhat difficult to get all of the powder coated with the lemon and eucalyptus. Let this sit until the juice on the stove is ready.


When the juice has cooked, let cool and then using the fine mesh strainer, slowly start straining the liquid into a separate mug. This will take some time, you will have to rinse the strainer several times, while doing this. Slowly add the juice to the henna now, just add a little liquid at a time and keep stirring the lumps out. When you have achieved toothpaste consistency, you are done...as long as the lumps are gone. Now, let this paste sit for a bit until a dark skin has formed over the top. When this happens, the henna has magically released the dyes and is ready to use. I realize it's not magical, but more scientific, but hey...what can I say, I prefer to think of it as magic.

Now, put a baggie in a cup so that it is open and in the cup like a liner.  Then take the nylon stocking (pantyhose) and stretch it over a cup and this will be inside the baggie now.  When it's taut, scoop the paste onto the center of the stocking and then just pull the stocking off of the cup, and you will have a big ball of paste dangling in the stretched panythose. Place this in a sandwich baggie, or a carrot bag. With one hand hold the baggie closed, while you begin to pull on the stocking. This will force the paste through the fine mesh of the nylon and strain out any bits that are still in there. When I have squeezed all the henna paste out of the nylon stocking, I slowly squeeze the air out of the baggie and tie it into a knot at the top. This way I can use it like a pastry bag by snipping the corner off and squeezing the paste through. Now, before I began using jacquard bottles, I only used baggies. I would snip a teeny bit of the corner off and use the baggie to apply the paste from. Now I prefer the bottles, so I snip a slightly bigger corner off and fill my bottles or cones this way.
There are many variations on this hot mix recipe. Try experimenting with
ingredients ON YOURSELF!  Here are some various things to try:

You will find the way that suits you and use that...then you will probably
begin experimenting with new things to add...like I do on occasion.

Sugar and Lemon Juice Fixative
This mixture is the most common for dabbing on the damp paste to keep it
moist and help secure it to your skin. I like to mix mine a bit sweeter than
usual as it make it more tacky and glue-glue like.

What you will need:
2tbsp sugar (or jaggery)
  • 2tbsp lemon juice
  • Mix thoroughly until the sugar is all liquified in the juice.  I store the extra in the
    fridge until I need it again and it will last a very long time this way.


    I have begun purchasing the large bottle of lemon juice concentrate, and
    simmering clove and cardamom in the juice for a couple of hours.  I leave 
    the cloves/cardamom in the lemon juice because I like to see them floating.
                   Aftercare for your Mehendi
    After you have applied the lemon juice/sugar fixative to your mehendi
    design, what next??? Well, here's the hard part for impatient people
    (I too fall in that group!)...

    You have some options on covering the paste, if you choose.
    1) tape a layer of toilet paper over the paste
    2) apply papertape (microfiber tape) directly over the design
    3) place a layer of toilet paper and then apply some clothing to the area
    (works best for feet/socks)

    4) this method is a bit more time intensive, but really helps keep the paste
    in place. After dabbing the paste with the lemon/sugar fixative a few times,
    allowing to dry in between, lay squares of 1-Ply toilet paper on the sticky
    paste. One at a time, with the toilet paper. Apply the toilet paper, then dab
    more lemon/sugar fixative over that, then move to the next part of the
    design and apply another square of toilet paper, then dab with more
    lemon/sugar fixative...etx, until you have covered not only the design,
    but around it by an inch or two. When this toilet paper/lemon/sugar/henna
    paste is tacky, I then (depending on what I have at the time) wrap it in
    gauze, papertape, or more toilet paper...and tape down.
    When it's time to remove the paste, the toilet paper will have hardened somewhat and usually pulls the paste right off.
    OR....just leave it uncovered.

    The purpose is not only to keep the design from getting marred, but also to keep the heat in on your design. Heat is important for getting a good stain on the skin, so whatever method you choose, just remember to try to keep the area that has the paste on, as warm as you can.

    After 4-5 hours you can take the paste off, although it is recommended that you keep the paste on for as long as you can, overnight is easiest to do. When you are ready to take the paste off, you can use steam to loosen the paste and just keep wiping it off with a towel until the paste is removed. Another method is to use the dull side of a butter knife, laminated card, or fingernail to scrape the paste off of your skin. Also, applying lotion to the paste and working it in, will help to loosen the paste and remove it from your skin. When the paste is removed you will have an orange-brown stain on your skin.

    Once you have removed the paste, DO NOT wash the area with soap and water. It is best for the longevity of the mehendi to avoid water contact for at least 12 hours. Which is sometimes unavoidable, but it is something to keep in mind when having mehendi done. After 48 hours your design will peak to it's darkest, and then over the next few weeks it will gradually lighten.

    Remember...The henna paste stains about 1/3 to 1/2 of the upper layers of your skin. As your skin regenerates the dead cells slough off, when this happens your mehendi design will keep lightening until it is gone.
    Enjoy your experimenting ... find what works for you! Happy Henna-ing to you!
