Hair pigmentation is regulated by melanin, a natural pigment synthesized by melanocyte cells located in the hair follicle. As individuals age or undergo oxidative stress, experience nutritional deficiencies, face hormonal imbalances, or are influenced by genetic factors, the activity of melanocytes may diminish. This decline leads to a reduction in melanin production, resulting in hair strands that grow devoid of pigment, ultimately causing gray or white hair. Premature graying can be associated with stress, deficiencies in vitamins (such as B12), lifestyle choices, and exposure to environmental factors. Promoting hair health through a balanced diet, effective stress management, and overall wellness is essential for preserving natural pigmentation.
