no it doesn't help anyone. if you wanted to help someone you would just say what's wrong with them and let them know how to fix it, e.g. suggest a good barber to get a good haircut from etc. there's nothing wrong with a bit of banter, e.g. if someone's bag has a bit of pink on it you make a joke about it, but it doesn't mean you should ostracise them for it and you should expect some banter in return later.
