Hi,My age is 28 years and i was diagnosed with male pattern baldness around 3 yrs ago. The doctor told me that it is because of hereditary reasons and has been aggravated due to change of water as i had shifted to Bangalore around 5 yrs back. I also took a treatment for about an year after during which my hair loss stopped.But i suppose this is an irreversible process and in order to avoid any hair loss in future:
1. i want to know that apart from a proper diet, what else i can do for this?
2. I suppose the water here in Bangalore is very hard, but i have been using this water for almost 5 years now, so is my scalp and hair not used to it by now? Is using this water to wash my hair still a danger now also ? Would it be advisable to shift to soft/packaged drinking water for washing hair? I used it for last 2 weeks and noticed that hair becomes soft but totally flat, now my doubt is that again a "change of water" from hard (which i am used to) to soft might lead to hair loss.

3. I might shift from Bangalore to a new place in future, what is the best way to save my hair from thinning and any further hair loss?
