Hi, I live in Argentina and the building is not that old, but the water here has a lot of lead in it. If the pipes are make of copper, I'm unaware of it. In the last couple months my hair started to fall out. I don't know if it's the water, and if it is, if I need to put a filter on it. I've lived here for several years and moved into my current apartment six months ago, but the hair loss started two months ago.
