New Delhi: Herbal hair dyes and fairness creams are found to be harmful to the skin as they contain “allergy-causing agents”. This was stated in the latest study that was conducted by the All India Institute of Medical Sciences (AIIMS), Delhi which led to the revelation of the presence of harmful preservatives and antioxidants in skin lightening creams, while hair dyes are positive with allergic contact dermatitis (ACD).
Since the cosmetic industry refrains from revealing what ‘kind of ingredients’ are being used in their products, it creates a major concern for the researchers. Over 106 patients were examined by the researchers who complained of skin diseases.
Riti Bhatia, Dermatologist, AIIMS, Rishikesh talked about the patch test they did on all the patients who had classical cosmetic dermatitis and the ones with induced skin darkening (pigmented cosmetic dermatitis). She said that redness, itching, making the face skin and neck become brown and later slate grey are the most common symptoms.
Professor and head of Dermatology department at AIIMS, Dr. VK Sharma, told ANI that over 77 patients were positive with allergy-causing agents like cetrimonium, gallate mix, and thiomerosal (a preservative that contains mercury). This is generally contained in the skin fairness creams and PPD (p-phenylenediamine) allergic element is present in herbal hair dyes.
The most troublesome and worrying aspect is that herbal hair dyes do not mention the presence of PPD in their labels. Professor Sharma spoke about their plans to write to the government for more regulation in the cosmetics, such that, companies should declare all the ingredients they are using in cosmetic products.
According to the experts from AIIMS, dermatitis is most commonly caused by cosmetics and women (about 13-18 percent of them) are affected after using it which is more than that of men.
