Mani coming out while making ghusal

Q: I have a problem of urine drops coming out of my body after urination. Similarly when ghusal is farz on me after dream at night and I am in shower doing ghusal, many drops of mazi or mani come out of my body, even during ghusal. What shall I do in such a situation? Shall I repeat my ghusal right from the start or continue doing it and finish it? 

Are hair roots impure?

Q: Is the root of the hair najis? And if so, what does this really mean? Since the hair that the body has naturally shed has the root intact (as opposed to cut hair), do I then assume that all hair that I see on the floor or in the bathroom has a part of it that is najis?

As a consequence, if I am eating soup or drinking water, and some hair falls in, does that make the entire liquid najis? If some fallen hair on the floor sticks to my wet foot, do I have to wash my foot? How exactly is the najasat of the hair root transferred?
