What is Henna?

Henna is a natural dye that is made from the leaves of the henna plant. The leaves are dried and ground into a fine powder, which is then mixed with water to form a paste. This paste is then applied to the hair, where it can provide a range of shades from light reddish-brown to a deep, rich burgundy color.

How to Apply Henna to Hair?

Before applying henna to your hair, it is important to do a patch test to ensure that you are not allergic to it. Once you have determined that you are not allergic, follow these steps to apply henna to your hair:

  1. Mix the henna powder with water to form a thick paste. You can also add other ingredients like lemon juice or tea to enhance the color.
  2. Section your hair and apply the paste from the roots to the tips using a brush or your hands.
  3. Cover your hair with a shower cap or plastic wrap and let the henna sit for 2-6 hours, depending on the desired shade and the natural color of your hair.
  4. Rinse the henna off with water and shampoo. Avoid using a conditioner as it can strip away the color.

Henna contains Lawsone molecules that bind to the proteins in the skin, hair, or any other material it comes into contact with. This binding process creates the stain or color. When henna paste is applied, it leaves a wet orange stain on the skin. However, the true color of henna develops over a period of 48 hours through oxidation. As the Lawsone molecules react with the oxygen in the air, the stain gradually deepens, resulting in darker shades.

Factors Affecting the Darkening of Henna

  1. Setting Time: The duration for which the henna paste is left on the skin plays a significant role in determining the final color. The longer the paste remains on the skin, the darker the stain will be. Ideally, it is recommended to keep the paste on for a minimum of 4 to 6 hours to achieve a rich, dark color.
  2. Aftercare: Proper aftercare is crucial to obtaining a beautiful dark stain. After the desired setting time has passed, the dried henna paste should be gently scraped off. To remove any stubborn bits, applying coconut oil and gently massaging the area can be helpful. It is important to avoid getting the design wet for at least 12 hours after scraping off the paste, as moisture can interfere with the oxidation process and affect the final color.
  3. Ingredients: The choice of ingredients used in the henna paste can also influence the darkness of the stain. Mixing henna with alkaline or acidic substances can darken its color. For example, adding pure lemon juice to the henna powder and applying it to the skin can result in a darker stain. Additionally, incorporating essential oils like lemon oil, eucalyptus oil, or clove oil into the henna paste can enhance the darkness of the color.
  4. Application Time: The time taken to apply henna plays a role in the final color achieved. The longer the application time, the more intricate and detailed the design can be. However, if you are looking for a quick application, henna can be applied in as little as one minute. The design complexity and the desired outcome determine the application time.

Duration of Henna Color

The longevity of henna color varies depending on various factors such as the body part where it is applied and how well aftercare instructions are followed. On average, henna color can last between one to two weeks. The color tends to fade gradually as the top layer of the skin naturally exfoliates over time. However, to prolong the vibrancy of the henna design, it is advisable to avoid excessive exposure to water, scrubbing the area, or applying lotions or oils directly on the design.


Henna is a beautiful natural dye that transforms from an initial orange hue to dark maroon or brown shades over time. The color development process relies on factors such as the setting time, aftercare practices, choice of ingredients, and application duration. By understanding and implementing these factors effectively, one can achieve a rich, dark henna stain that enhances the beauty of body art. Remember to follow proper aftercare instructions to maintain the longevity of the henna design and enjoy its beauty for an extended period.
