What are the causes of white hair on the top of a woman's head?

Generally, the causes of white hair on the scalp in women may include aging, frequent late-night habits, excessive stress, malnutrition, vitiligo, and other factors. If any discomfort occurs, women are advised to seek medical treatment promptly. Detailed analysis is as follows:

1. Aging: Melanin is the key substance determining hair color. With age, melanocyte activity gradually declines, causing hair color to fade and eventually turn gray or white. This is a natural physiological process that nearly everyone experiences.

2. Frequent late nights: Long-term sleep deprivation disrupts the body's biological clock and affects normal endocrine and metabolic functions, potentially impairing melanocyte function and thus influencing hair color. It is recommended to maintain 7–8 hours of sleep daily and adopt a routine of going to bed early and waking up early.

3. Excessive stress: Prolonged high-stress states can affect the neuroendocrine system, possibly damaging melanocyte function. Additionally, chronic stress may trigger various physical and psychological issues such as insomnia and anxiety, which could indirectly contribute to premature graying. Stress reduction through listening to music, moderate exercise, and other relaxation techniques is recommended.

4. Malnutrition: Hair growth and color maintenance require various nutrients, including proteins, vitamin B complex, iron, zinc, and others. Deficiencies in these nutrients may lead to lighter hair color or even white hair. It is advisable to consume more fresh vegetables and fruits regularly to help replenish essential nutrients.

5. Vitiligo: Vitiligo is a skin condition caused by damage to or loss of melanocytes. When vitiligo affects the scalp, it can impact hair pigmentation, causing hair to turn white. Treatment options may include medications such as bailing tablets, qubai babuqi tablets, or methoxsalen tablets, as prescribed by a physician.

In daily life, maintaining a cheerful mood and emotional balance is recommended, as this can help reduce the occurrence of white hair.
