Patient's question:
For years. Increasing year by year.Doctor's answer:
Western medicine refers to it as premature graying of hair, a condition characterized by the occurrence of white hair during childhood and youth. Its etiology is highly complex, with two major types: congenital premature graying and acquired premature graying. Among the acquired types, many are associated with certain diseases, while others result from excessive mental stress and malnutrition.Traditional Chinese medicine holds that hair is closely related to qi—specifically, original qi, congenital qi, and nutritive qi. Maintaining a dynamic balance among these three types of qi is essential for normal and healthy skin and hair. If one type of qi is deficient, it can disrupt the functioning of the others. If two types of qi are impaired, it inevitably leads to damage to the skin, causing it to lose its normal structure and properties, manifesting as varying degrees of pathology.
Many diseases can be accompanied by premature graying, such as pernicious anemia, hyperthyroidism, cardiovascular diseases (e.g., myocardial infarction, bundle branch block, hypertension), nutritional myopathy, vitiligo, and Vogt-Koyanagi-Harada syndrome, among others. Additionally, changes in mental state, such as prolonged depression, excessive worry, or extreme mental tension and panic, can cause hair to turn white rapidly. The aforementioned diseases, as well as nutritional and psychological factors, disrupt the balance of original qi, congenital qi, and nutritive qi, leading to hair damage. This is what we colloquially refer to as "damaged qi." Premature graying of hair does not require special treatment; identifying and addressing the root cause is sufficient for a cure.
As for congenital premature graying, it is mostly caused by genetics. Conditions such as genetic progeria, Bockhart syndrome, and Waardenburg syndrome often have a history of multi-generational inheritance within families. Genetic defects and albinism are also congenital genetic disorders. Except for acquired abnormalities, which are localized skin diseases of the acquired type that often normalize within months or years, these causes of premature graying are due to genetic mutations that block the tyrosine metabolic pathway entirely (as in albinism) or locally.
