I took a temporary work assignment in Washington DC and within days of settling into my new apartment, noticed more hair appearing in my hair brush, to the point I was cleaning the hair from the brush daily. This went on for five months.
I thought it might be my hair products so I changed them with no improvement. I'd always had thick hair and thought my hair loss had to be connected with the move. One day, I was searching the internet and thought I'd try washing my hair with bottled water. The first time I used the bottled water, my hair stopped falling out immediately. Now after 11 months in DC, I have to say my hair is back to normal. It's a little bit of a hassle heating and using bottled water, but considering the alternative, I'll be a little inconvenienced.
