Melanin is what gives color to human skin, eyes, and hair. It’s the ratio of two types of melanin—eumelanin and pheomelanin—that determines your natural hair color. And it’s the size and shape that the melanin molecules form when they cluster in the hair shaft that give the unique tones within a hair color.

In comparison to natural hair dyes, synthetic hair dyes are reported to cause skin and other skin related diseases. The manufacturing process is hazardous to health of the people involved in the process and its applications leads to environmental pollution and also causes potential side effects to the consumers of the product.

 

The increase in environmental and health hazards in the manufacture of dyes and its use throughout world is a major concern. This work was made possible while investigating the alternative to the synthetic and semi synthetic dyes.The composition of 100% herbal hair dye.

 

A dye can generally be described as a colored substance that has an affinity to the fiber, fur or hair. The dye is generally applied as aqueous solution, and may require a mordant to improve the fastness of the dye on the fiber, fur or hair. Natural dyes also referred as mordant dyes. Different mordant will give different hue color with the same dye. A mordant is thus an agent which allows a reaction to occur between

the dye and the fiber, hair or fur

 

Hair dyes include dyes modifiers, antioxidants, alkalizers, soaps, ammonia, wetting agents, fragrance, and a variety of other chemicals used in small amounts that impart special qualities to hair such as softening the texture or give a desired action to the dye. The chemicals that are normally used in the dye are amino compounds (4-amino-2-hydroxytoluene and m-Aminophenol). Metal oxides, such as titanium dioxide and iron oxide, are also often used as colorants in the process.

Continuous usage of such compounds containing dye on natural hair causes so many side effects such as skin irritation, erythrema, loss or damage of hair and skin cancer.

Graying of hair is natural phenomenon attributable to ageing and frequent use of synthetic shampoos which are encouraged application of synthetic dyes with the increase in the use age of hazards chemicals in the process of manufacturing hence an attempt has been made to review the use of natural products obtained from plants sources to replace the synthetic dyes.

Beauty is a multi-billion-dollar industry that’s continuing to grow. According to one industry report, cosmetics manufacturing will have brought in $255 billion in revenue globally in 2014. The industry remained stable through the recession and, as incomes increase with recovery, demand for high-priced beauty products means that global profits are estimated to increase to $316 billion by 2019.

Globally, hair-care products are the largest portion of the beauty industry and secure nearly a quarter of industry revenue. In the U.S., within hair and nail salons, hair-coloring services account for 18 percent of revenue. An estimated 70 percent of women in the U.S. use hair-coloring products global profits are estimated to increase to $316 billion by 2019.

Ancient Egyptians dyed their hair, but rarely did so while it was on their heads. They shaved it off, then curled and braided it to fashion wigs to protect their bald heads from the sun. Black was the most popular color until around the 12th century BCE, when plant material was used to color the wigs red, blue, or green, and gold powder was used to create yellow. Of natural dyes, henna endures.

The ancients also used saffron, indigo, and alfalfa. But natural dyes only coat the hair temporarily, and people wanted chemically altered tresses. Analyzing hair samples has revealed that the Greeks and Romans used permanent black hair dye thousands of years ago. They mixed substances that we know today as lead oxide and calcium hydroxide to create a lead sulfide nanoparticle, which forms when the chemicals interact with sulfur linkages in keratin, a protein in hair.

When the direct application of lead proved too toxic, the Romans changed their black dye formula to one made by fermenting leeches for two months in a lead vessel.
