A lot of people like to get their photo done to show of their new hair-cut, and some even get their hair cut in specific anticipation of a photograph.
Some even cut it themselves. Either way, this is a mistake, it looks unnatural. When people subsequently meet you, they will say, His hair is not quite the same. He looked quite friendly in the photograph, but when we me him he was dour and dishevelled. He had a slight smell which we discussed at length but couldn’t place. We had expected him to smell of freshly cut hair, but in the event were to be disappointed.
