Cosmetic Trichology: Hair Cosmetics, Styling, and Their Effect on the Hair Fiber

The article discussed the impact of various hair styling procedures on hair morphology, highlighting the significant growth of the cosmetic industry in India. It emphasized that modern hair cosmetics are expected to perform multiple functions beyond cleansing, such as preventing baldness and enhancing shine. However, these procedures can cause long-term damage to hair fibers, particularly through a "Weathering-Erosion model" where repeated treatments weaken the cuticle, making the hair shaft prone to damage. The study noted that deep conditioners and hair oils did not prevent hair breakage, contrary to some literature suggesting protein-based conditioners and oils can restore cuticular integrity. Dermatologists need to understand esthetic trichology to mitigate adverse effects from aggressive cosmetic use.
