“…Global scenario is now shifting towards the use of safer, nontoxic natural product with traditional use, attempts are required to develop herbal hair dye devoid of any chemical, containing few traditionally used herbs and modifiers. It is seen that hair dyes with herbal ingredients are prominently in use in south east Asia and it is getting acceptance in other developed markets like EU and Americas (12).…”

Introduction: Colour of hair is most conspicuous phenotype of human beings and plays an important role in one's overall physical beauty. Premature hair greying (PHG) has caused the increased use of various hair dyes in population though it has adverse effects. Aim- To assess knowledge, practice of hair dye users with purpose, frequency of use and adverse reactions if any on hair, scalp, skin. Methodology: A cross-sectional study was conducted on participants from PCMC region by interview method using a questionnaire (20 questions) specially prepared pertaining to use of hair dye and adverse reactions to it. Statistical Analysis-The demographic data is expressed as mean ± standard deviation, quantitative data expressed as percentages. Results: A total 98subjects including 75.5% and 24.5% females and males respectively. The participants started using hair dye at an age of 25 (±3.03) years. Herbal and Synthetic dyes were used by 36.74% and 63.27% respectively. Frequency of use in a year was 4-5 times in 58.16%. Adverse reactions of dye on body of hair like dryness46.94%, loss of hair 30.62%, change in texture and thinning were reported. 29.59% of subjects showed ill effects during dyeing of scalp while in 68.36% of subjects after the dyeing process was complete. Conclusion: Majority Population started hair dyeing at very early age using Chemical dyes even though they perceived herbal dyes were safe. They continued hair colouring despite adverse reactions, which indicates aesthetic importance of hair colour and need of research in the field of Ayurveda for developing safe, natural hair dye.

One of the oldest and most well-known cosmetics, hair color has been used by numerous ancient cultures throughout history on both men and women. It involves treating hair with various chemical compounds for changing hair color. According to how long they remain in the hair, these products are primarily divided into two categories: temporary and permanent. This classification is consistent with the types of active substances used in the dyeing process as well as the dyeing method itself, which are referred to as non-oxidative and oxidative hair dye products, respectively. Permanent hair dyes often consist of active chemicals that are not dyed but are oxidized to provide the desired color. As a result, the phrase "oxidative hair dye" was emerged. The precursor part and coupler part are the two main ingredients in formulations for oxidative hair dyes. Quinonediimine intermediates are momentary compounds that are generated when combined with hydrogen peroxide (developer). As a result, the coupler agent and these compounds interact to form the appropriate hair dye molecule. Notably, the entire dyeing process requires both an alkaline medium and an oxidizing agent, often hydrogen peroxide, to ensure that the staining agents reach the cuticle widely. This review's objective is to provide information about hair dye formulations and mechanisms of action as well as repairing damaged hair and new applications.
