Water and Hair Loss

I am curious to know whether water would be an issue in hair loss. I am currently in Spain. I have been here since September and am not coming back to the states till August. I recently started taking generic finasteride at the beggining of this month should I be concerned about water and its pertinence towards hair loss, as well would the 5mg generic finasteride have exactly the same ingredients as the propecia?

Unless there is something I do not know about the water in Spain, it should not be a cause of hair loss.

Generic finasteride in 5mg strength is FIVE times more potent than Propecia, which contain 1mg of finasteride. Thus, if you are using finasteride in 5mg strength you should cut it (ideally in 5 pieces, but realistically in 4 pieces) to make 1mg of finasteride. Taking 5mg finasteride at once is NOT more effective than taking 1mg of finasteride for treating hair loss. In fact, you may have an increase in the incidence of side effects.
