For millennia, henna's beautiful, natural colours and healing qualities have fascinated people. As people look for healthier and safer alternatives to chemical-filled hair colours, this age-old herbal remedy has recently seen a rebirth. The rising popularity of henna hair colouring reflects a trend toward appreciating the natural world and putting one's health first.

Which plant is used to make Henna hair dyes?

The Lawsonia Inermis plant is the main ingredient of Henna hair colours. Due to its rare leaf pigment, this plant has been farmed since ancient times in tropical and subtropical regions, including Africa, India, and Australia. Henna leaves contain Lawsone, a reddish-brown pigment that is the plant's main dye.

The pigment is isolated by sun-drying or controlled dehydration of brown leaves. The drying process is when Lawsone is in its highest concentration, which is why hair colourants are so intense. After drying, the leaves are pulverised into a fine powder that creates reddish-brown to auburn henna hair tints.

NOTE: Different plants, like the Cassia leaf powder, are mixed with Lawsonia Inermis plant powders to create a lighter shade for the hair.

How are Henna Hair Dyes Manufactured?

Step 1: Grinding the Henna Leaves

Henna powder is used as a derivative in hair dye production. Dried henna leaves are fed into a specialised pulveriser that grinds them into a fine powder. This ensures that the Lawsone pigment is spread evenly in the powder, which in turn ensures that the hair dye colour is consistent.

Step 2: Adding Dyes

Dyes may be added to the henna leaf powder to develop hair dye products as per the desired shade – natural black, brown or dark brown.  Eucalyptus, lemon, and lavender essential oils are used for fragrance and hair conditioning. Indigo, cassia, and amla could be included in henna powder to modify its colour or make it more useful.

Step 3: Mixing and Blending

Firstly, the henna powder and the additional ingredients are correctly weighed to balance the dye's shade and then thoroughly mixed. This phase ensures a uniform mixture by evenly sharing the elements while keeping them homogeneous.

Step 4: Packaging

The blended henna hair colour mixture is packed in sealed containers or sachets to maintain its efficacy and limit moisture exposure.

Step 5: Quality Control and Certifications

To fulfil high standards, ingredients must be tested for their purity and consistency. Similarly the finished product must also be rigorously tested to ensure compliance of quality standards. It is always beneficial for the manufacturing unit to be audited regularly for ISO or GMP standards.
