Hair Cosmetics

The 2013 article "Hair cosmetics" by Nina Madnani and Kaleem Khan reviewed the advancements in hair cosmetic products and their implications for hair care and dermatology, particularly in the Indian context. It covered the evolution of hair cosmetics to cater to various hair types and the importance of understanding hair structure for proper care. The paper detailed the ingredients and classifications of shampoos, conditioners, and other styling products, and discussed the traditional practice of hair oiling in India. It also addressed the safety and side effects of hair dyes, highlighting the allergenic potential of para-phenylenediamine (PPD) and the regulations limiting its concentration. The document noted the lack of a causal relationship between personal hair dye use and cancer, but acknowledged the higher risks for hairdressers. Additionally, it discussed the risks associated with hair straightening, perming, and dyeing, and the need for dermatologists to be aware of the latest products and potential adverse effects. Innovations in hair cosmetics, such as formaldehyde-free straightening products and new hair coloring methods, were also mentioned.
