It is far more likely that Posey cut his hair again AFTER he found out when they would be starting back - it's part of his contract to maintain his appearance.

The "delay" narrative is based on what Posey said (on Being Tyler Posey) on the final day of production for Season 4. It is assumed that the original plan was to return to work before the end of the year - but that date was never announced beyond Posey's statement.

As to the writers - they just came back together after the break at the end of October.

How long do you think it takes to plot out a season of television and then write enough to begin pre-production and then get it in front of the cameras? It doesn't happen fast.
