First, No, it doesn't (and someone doesn't need to be living with HIV to know that) . Second, that's an offensive question. Third, as you can read in a multitude of posts on this site and elsewhere, symptoms are never a way to determine if one has HIV since there are NO HIV specific symptoms as you were told in the first response. The answer doesn't change if you ask symptom by symptom.
does it make your toe nails black and your hair thin?
No, because neither have specific symptoms. AIDS definition is when ones CD4 drops down to 200 or less or one has a low CD4 but also has an O.I. Once you are in the AIDS classification it no longer matters how high you CD4 level gets, your classification will stay as having AIDS. If you don't care for the term AIDS, you can use Advance HIV Disease it means the same.
