Hi , one question, does XXXXXXX water causes gray hair
Regarding greying of hair
Hello and welcome to ask a doctor service. I have reviewed your query and here is my advice.
XXXXXXX water application doesn't cause white hair. Infact it is quite normal for black hair to start turn grey hair as we age. I noticed that your age is 45. So its not surprising to have some grey beard hair.
Hope I have answered your query. Let me know if you need any more assistance
