Meaning ❉ Nutritional Trichology considers the deep connection between internal bodily health and the specific well-being of hair, particularly for coily, kinky, and wavy textures. This field applies principles of dietary science and nutrient absorption to the unique physiological needs of textured hair, supporting its structural integrity and vitality from within. Understanding how specific vitamins, minerals, and macronutrients influence the hair growth cycle and strand composition allows for a systematic approach to hair care. It offers a framework for consistent internal support, much like a well-calibrated system, moving beyond topical solutions to address foundational health. Practical application involves making informed dietary choices and considering supplementation to support length retention, minimize breakage, and maintain the inherent strength and luster characteristic of Black and mixed-heritage hair. This approach acknowledges that true hair resilience begins with the body’s internal balance, offering steady guidance for consistent, visible hair health improvements.
