What should a 14-year-old girl do if she has gray hair?

A 14-year-old girl developing white hair may be due to genetic factors, high mental stress, nutritional imbalances, vitamin B12 deficiency, or hypothyroidism. Symptoms can be improved through emotional regulation, nutritional supplementation, and medical treatment. If white hair rapidly increases or is accompanied by fatigue and cold intolerance, prompt medical attention is necessary.

1. Genetic factors: A family history of premature graying may lead to early onset of white hair in adolescents, typically without other discomforts. Temporary improvement in appearance can be achieved through hair dyeing, but frequent coloring and heat styling should be avoided to prevent hair damage and minimize pulling on areas with white hair.

2. High mental stress: Academic pressure or emotional tension can cause endocrine disorders, affecting melanin production and leading to white hair, possibly accompanied by insomnia and anxiety. It is recommended to maintain a regular sleep schedule, relieve stress through exercise and talking with others, and avoid excessive late nights.

3. Nutritional imbalance: Deficiency in protein, B vitamins, and other nutrients can impair melanin synthesis, resulting in white hair, along with pallor and easy fatigue. It is advised to adjust the diet by consuming more eggs, lean meat, nuts, and dark green vegetables to ensure comprehensive nutrition.

4. Vitamin B12 deficiency: Insufficient intake or impaired absorption of vitamin B12 affects the nervous system and melanin production, causing white hair, along with dizziness and difficulty concentrating. It is recommended to take vitamin B12 tablets, mecobalamin, folic acid, and other medications under medical supervision to improve symptoms.

5. Hypothyroidism: Insufficient thyroid hormone secretion slows metabolism and impairs melanocyte function, leading to white hair, accompanied by cold intolerance, fatigue, and weight gain. Treatment may include levothyroxine sodium tablets, vitamin E soft capsules, and compound vitamin B tablets, as directed by a physician.

Daily care should include maintaining a regular作息 (sleep-wake) cycle, avoiding late nights, reducing mental stress, eating a balanced diet rich in nutrients, using gentle shampoo products, and minimizing hair damage.
