The surface skin of the ear contains follicular glands like other parts of the skin structure, and hair grows in the follicular glands. If there is a white hair on the ear, it may be related to the age, but also may be related to the lack of trace elements, local inflammation and infection, endocrine disorders and other factors.
1. Micronutrient deficiency: If the usual diet is too single, or there are picky eaters, partiality, etc., it may lead to micronutrient deficiency, which may lead to hair loss, dull color, insomnia, menstrual disorders, etc. At the same time, due to the melanin degradation of the hair, the follicular glands of the hairs may be damaged. At the same time, due to the degeneration of melanin in the hair, white hair may be formed.
2. Local inflammation and infection: Due to the inflammation and infection of the corresponding hair follicle glands, the function of the hair follicle may be destroyed, affecting the growth of hair as well as the formation of melanin, and there may even be hair loss. It may manifest as white hair growth.
3. Endocrine disorders: endocrine hormone disorders in the human body caused by poor living habits, dietary habits, etc., which leads to a decrease in melanin secretion in the body, may also cause white hair growth behind the ear.
To summarize, when a white hair grows on the ear, if there is no discomfort, there is no need to worry about it, and you can also go to the hospital to be fully examined by the receiving doctor to rule out the relevant lesions.
