What color does Colorless Henna dye hair?

Posted by Yuki Katakami on

Cassia Obovata, also known as Colorless Henna or Neutral Henna, is renowned for its health benefits for hair and scalp. One of the primary benefits is its excellent cleansing effect, likely due to its antibacterial properties. Additionally, Cassia Obovata binds to the keratin in hair, offering protection from UV rays.

Health Benefits Without Dyeing Your Hair
Many people seek the health benefits of Cassia Obovata without the concern of dyeing their hair. While Cassia Obovata does not alter the color of dark hair, it is said to impart a light golden hue to gray and blonde hair. To explore this, I conducted a simple experiment to see how it affects different hair colors.

Experiment: Dyeing Hair with 100% Organic Cassia Obovata Leaf Powder
I used 100% organic Cassia Obovata leaf powder to dye gray and brown hair. Here's the process I followed:

Preparing the Paste:
Dissolve Cassia Obovata leaf powder in water. 

It's important to note that the powder doesn't dissolve easily, so thorough stirring is essential to create a smooth paste.

Applying the Paste:
Apply the Cassia Obovata leaf paste to the hair sample and let it sit for about an hour.

Observing the Results:
After an hour, I observed the color changes.

Brown Hair: There was no noticeable change in color.
Gray Hair: The gray hair became slightly darker, but the difference was almost indistinguishable.
After an hour of dyeing, the color change was minimal, even under magnification. This minimal color change is why Cassia Obovata is often referred to as Colorless Henna.

Cassia Obovata Leaf Powder is an excellent choice for those who want to reap the health benefits for their hair and scalp without changing their hair color. It provides a natural, non-dyeing treatment that can enhance the overall health of your hair. If you’re looking for a natural hair pack that offers protection and cleansing without the risk of dyeing, Cassia Obovata is highly recommended.
