“I don’t believe the covering of hair is associated with the “loss of innocence”, but will drop the subject and get back to boys wearing shorts”
umm… apushuteyid, i suggest you take a look at Rav Falk’s sefer,
also Moq, very good point (previous post of yours) if i’m correct i think it’s Rav Moshe who says that that’s why a kallah doesn’t have to cover her hair till the next morning.
