>>727 >>729 Wigs can be applied on any length of hair. If he cut it, it was simply because he wanted to. He probably used the hairdressers on set when he visited out of convenience. Usually all cuts and colors are 'in- house' (not outsourced) since cast members don't have time to visit salons and they want to maintain lengths/ colors.
I preferred the blended hair too but I imagine he refuses to color his hair any more than is absolutely necessary in fear of more falling out
