Patient reports:  I believe that I was a victim of hair loss in the few months that I was given Oxycodone/Norco medication for my back pain.  My hair has not grown back.

It is not generally believed that these two medications can cause hair loss; nevertheless, with your comments as well as a few similar comments on a recent Google search (I suspect like all medications), hair loss is always a risk, even if it is a small risk.
