Can the old man's white hair turn blackJudging from the current situation, there were many possibilities for the elderly to turn from white hair to black hair. On the one hand, there may be misunderstandings in some cases. Because hair has a growth cycle, when the white hair of the elderly falls off and the black hair grows back, it may be mistaken for white hair turning black; dyeing hair will also cause the visual effect of white hair turning black. On the other hand, if the nutrition of the elderly was improved, the mental stress was reduced, or the disease that caused white hair was controlled, black hair might grow back. However, according to the current level of technology, there was no product that could really make the hair that had turned white grow black hair again. Moreover, the change of white hair to black hair in the elderly may be related to the disease. This situation should be checked in time.

20 years old, white hairGrey hair at the age of 20 could be caused by many factors.
** 1. Genetic factors **

** 5. Disease factors **
1. Some acquired diseases such as hypothyreosis, copper metabolism disorder, vitiligo, white hair, and auto-immune pernicious leukemia may cause hair to turn white.
2. Some congenital diseases, such as albinism, mottled disease, and pheketonuria, could also affect the production of dark matter, causing hair to turn white.
