What causes white hair in children?

Generally, the causes of white hair in children may include heredity, mental factors, vitamin B12 deficiency, hyperthyroidism, vitiligo, and so on. If there is any discomfort, timely medical consultation is recommended. Detailed analysis is as follows:

1. Heredity

If there is a family history of premature graying, especially if parents or ancestors had gray hair at a young age, the likelihood of a child developing white hair significantly increases. Adjusting lifestyle habits and dietary structure may help delay the progression of white hair.

2. Mental Factors

Long-term mental stress, anxiety, and other negative emotions may cause endocrine disorders, affecting melanin synthesis and distribution, thereby leading to white hair in children. Parents should provide sufficient care and support to help children develop a positive mindset. Encourage children to participate in activities they find interesting to distract their attention and relieve mental stress.

3. Vitamin B12 Deficiency

An unbalanced diet can lead to vitamin B12 deficiency, which affects DNA synthesis and cell division, subsequently impairing the normal function of melanocytes and causing hair to lose its color. Dietary adjustments are necessary to increase intake of foods rich in vitamin B12, such as animal liver, eggs, and dairy products.

4. Hyperthyroidism

Hyperthyroidism is usually caused by heredity or chronic late-night sleep deprivation, leading to excessive secretion of thyroid hormones in the body, which affects melanin synthesis and distribution, thus causing white hair in children. Symptoms may also include palpitations, excessive sweating, weight loss, and exophthalmos (bulging eyes). It is recommended to follow medical advice to take medications such as propylthiouracil tablets, methylthiouracil tablets, or methylprednisolone tablets for treatment.

5. Vitiligo

Vitiligo occurs when the body's immune system mistakenly attacks its own tissues and organs, damaging pigment cells, resulting in hair losing its color and turning white. Skin itching may also be present. Under a doctor's guidance, medications such as calcipotriol ointment, tacalcitol ointment, or tacrolimus ointment can be used for treatment.

In daily life, it is important to ensure children maintain a balanced diet with adequate intake of vitamin B12-rich foods, pay attention to their mental well-being to avoid prolonged stress, and maintain regular sleep patterns to help prevent the occurrence of white hair.
