I think it would be inappropriate if it were the only thread in which something was being discussed. But it's not -there are what, thousands more?
I've wondered about the haircuts myself. It doesn't keep me up at night, but I've still wondered. The Amish, for instance, are not allowed to cut their hair but they still keep the ends trimmed. Like someone said, it doesn't make it grow faster, but it makes it look better and be easier to manage when the ends aren't straggly. I imagine that OTMA's hair was trimmed occasionally because it made it look nicer. Just as Romanov women were noted for their lovely hands, and therefore things were done to insure that they stayed lovely.
