My baby has a white hair on their head, what's going on?

Patient's question:

No

Doctor's answer:

Hello, having a few strands of white hair occasionally is fine, as it is caused by pigment loss. However, if the number increases, it should be noted.
Causes of white hair:
(1) Poor nutrition: Lack of protein, lack of vitamin B12, copper deficiency, iron deficiency, zinc deficiency
(2) Diseases: Albinism, phenylketonuria, Fanconi syndrome, pernicious anemia, thyroiditis, vitiligo
