I'm 28 years old male, residing in Bangalore. Since 2-3 years I have developed grey/white hairs. In the year 2013 till mid of 2015 I was in Hyderabad (where it was hard water) not sure if this is the cause of my hair turning white since then. However, I'm living back in Bangalore since mid of 2015 and I see the white hairs have been populating more. To get rid of awkwardness I've started cutting them as much as short I can being in-front of mirror. As of now the good thing is the white hairs are more in the 2nd layer of my hair and from outside only few white hairs are noticeable. But inside there are pretty lot. Is there a medication and solution for my problem?
