How to Apply Henna on Hair
Prepare for Application Henna
1.Mix the henna powder. Henna is sold in powder form and must be mixed with water before it can be applied to the hair. Pour 50 g of powder and 60 ml of hot water into a boule, then mix to mix them. If necessary, add more water, one tablespoon (15 ml) at a time, until you get a paste that has a consistency similar to that of mashed potatoes.
- When the water and powder are perfectly mixed, cover the boule with cling film and let the henna sit at room temperature for about 12 hours.
- Just before applying it to your hair, add a little more water so that the mixture remains thick, but is spreadable.
2.Shampoo and dry your hair. Henna should be applied to perfectly clean hair. Wash them as usual to remove dirt, sebum and residues of styling products. Rinse them thoroughly to remove all traces of shampoo, towel dry them and then let them air dry. If you want, you can also use the hairdryer.
- Do not use conditioner because oils and other moisturizing substances may prevent henna from penetrating deeply into the hair
3.Protect the surrounding skin. If you have long hair, gather it in a tail behind your head to keep it away from your face, neck and shoulders. If they are short, wear a band to have a free forehead. Apply an oily product along the hairline, for example coconut oil or shea butter. In addition to the forehead, also spread it on the nape and ears.
- The oil will create a barrier between henna and skin, thus preventing it from getting stained.
4.Comb your hair and line it in the middle. Untie the tail and use a wide tooth comb to comb them. In this way you will be able to remove the knots and avoid them becoming frizzy. At the end make the middle row and drop them evenly on both sides of the head.
- There is no need to divide them into different sections because you will proceed in layers.
5.Protect the skin. Henna tends to run, so it is advisable to wear cheap clothes and still protect them with an old towel. Place it on your shoulders and position it so that it also covers your neck; if necessary, hold it still with a clothespin.  Since henna can stain the skin, wear latex or rubber gloves to protect your hands and nails.
- You can also use a plastic or fabric cape like those of hairdressers.
- Keep a damp cloth handy with which to immediately eliminate any drops that have fallen on the skin.
1.Apply the mixture freely to a small section of hair. Start with the ones above. Take a lock about 5 cm wide from the central back of the head, separate it from the other hair with the help of the comb, then apply 1-2 tablespoons (2-4 g) of henna on the roots. You can use your fingers or a brush to do the tint. Distribute it gradually down to the tips, adding more if necessary.
- Henna does not spread as easily as normal dyes, so make sure your hair is completely saturated before continuing further.
2.Twist your hair and secure it near the head. When the first strand is completely covered with henna, twist it on itself a couple of times to create a small chignon, then secure it with a spout near the head. Henna is pretty sticky, so you won’t have a hard time keeping it in place.
- If you have short hair, twist the lock briefly and secure it with one or more bobby pins.
3.Apply henna on the next section. Continue with the top layer of hair; take another 5 cm wide section, next to the first. Apply henna on the roots with your fingers or brush, then gradually distribute it to the ends, adding more if necessary. Continue until the hair is completely saturated.
4.Twist and wrap the lock around the previously created bun. Wrap it on itself a couple of times, then roll it around the bun you created with the first strand of hair. Since henna is quite sticky, it’s likely that they will stay still without difficulty, but if you want you can fix them with another spout.
- If you have short hair, twist the lock and fix it on the first one with bobby pins.
5.Continue to apply henna on the rest of the hair. Proceed with one small section at a time, as you have done so far. Move to the forehead, applying henna to the hair on both sides of the head. Continue with locks no more than 5 cm wide to be able to distribute the mixture evenly. When you have finished the top layer of hair, repeat the same process with the bottom one and continue until you are done.
- Continue to twist and wrap the strands of hair around the original bun
6.Touch up your hair along the hairline. After each strand has been covered with henna and wrapped around the first bun, check the hair along the forehead, ears and nape of the neck and add other color where you deem it necessary. Finally, also check the remaining areas of the roots.
Laying and rinsing
1.Wrap your hair in plastic wrap. Once you’ve made the necessary adjustments, take a long sheet of film and wrap it around your head. The hair must be completely covered, including the roots at the hairline. Leave your ears out.
- Creating this film cover serves to keep the henna warm and humid, so that it can penetrate the hair correctly.
- If you need to go out during the shutter speed, wear a hat or wrap a scarf around your head.
2.Keep the henna warm and let it work. Generally, a shutter speed of 2 to 4 hours is required. The longer it stays on the hair, the more intense and vibrant the color will be. You can promote a better result by keeping the mixture warm. Stay indoors if it’s cold outside or wear a hat if you need to go out.
- Henna can be left on for up to six hours to achieve even more vivid reflections.
3.Remove henna with the help of balm. At the end of the shutter speed, put on the gloves again and remove the plastic cover from the hair. Enter the shower and rinse your head with plenty of water, then massage a little balm on the strands to be able to dissolve even the last residues.
- Continue to rinse and apply the conditioner until the water on the bottom of the tub is completely transparent and there is no trace of henna left on the hair.
4.Wait a few days for the color to develop fully. It takes about 48 hours for the results to fully manifest. When the hair dries for the first time, they will appear extremely shiny and with reflections that tend to orange. After a couple of days, the color will become darker and more intense.
5.Touch up the roots when hair grows. Henna is a permanent tint, so you don’t have to worry about it coming off with shampoo or that the color will fade. More or less once a month, you can reapply it on all hair to get even brighter reflections or only on regrowth.
- To touch up the regrowth, leave the henna on for the same time as the original application to achieve a similar color.
