The brain is also referred to as the forehead. A white hair on the forehead may be related to aging, heredity, and micronutrient deficiencies.
1. Aging: With age, the body’s physiological functions gradually decline, the function and activity of melanocytes decrease, which will lead to hair whitening.
2. Hereditary factors: if the hair turns gray during adolescence, it may be related to genetic factors.
3. Trace element deficiency: the lack of copper, zinc, iron and other trace elements will affect the color of the hair to a certain extent, which can be manifested as red, yellow or white hair and so on.
If there is only one gray hair, usually no special treatment. If a large number of hairs suddenly turn gray, it is recommended to consult a doctor for a clear diagnosis.
