Hair Graying

Ever wondered about the reasons behind why people experience premature graying of their hair? Hair graying represents a universal genetic aspect of aging that inevitably affects the majority of individuals throughout their lifespan. The biological process of gray hair development requires an understanding of both genetic and environmental influences although cultural perspectives mainly link gray hair to aging. Hair color extends beyond aesthetic appearance because its origin is firmly based in genetic components. Your hair color is determined by the melanin pigment quantity and type present in your hair follicles. The pigment melanin helps define both skin and eye color. The graying of hair occurs as we age through a steady reduction of melanin pigment. Genetic factors control the majority of individual variations in hair graying since they account for 30% to 90% of these differences. Genetics determine hair graying but environmental and lifestyle factors also affect when this change happens. Various elements including stress and cigarette smoking along with environmental exposure elements speed up hair graying. Obesity along with insufficient exercise and health disorders including high cholesterol levels and high uric acid concentrations have effects on early hair graying together with thyroid problems and liver diseases. While it may not be possible to completely stop hair from turning gray you can still take measures to decelerate the process. An active healthy lifestyle combined with proper stress management and smoking avoidance will help maintain your hair color for a longer period. Supporting overall health through physical activity and treatment of health conditions can help prolong natural hair color and delay gray hair development. PlexusDx offers Precision Health & Wellness tests that help you understand how your genetic predisposition to graying hair influences your health and longevity.
