azi,
Please. You are treading on thin ice. Did you read the new rules posted? One of them is specifically regarding Loshon Hara.
As far as your amartzus (and mods, there is no nicer way to put it — this is halacha) regarding the Aruch Hashulchan — The Aruch Hashulchan (Orech Chaim 75:8) specifically says that it is forbidden for a woman to go outside without her hair covered. He is maiked regarding it being considered erva when a man must say a bracha, as long as the man cannot see her hair while he is reciting the blessing. However, the Mishna Brura (75:10) strongly disagrees even with this leniency (that is anyways only applicable regarding a man reciting a bracha in her prescence) and forbids any blessing or prayers to be said in the presence of a married woman with her hair uncovered. This applies even to a husband in his own home if his wife has not fully covered her hair.
