If your hair is dry and you have not conditioned it then you are running the risk for splitting the ends. So to begin with, make sure that you shampoo well and use a conditioner unless of course your hair is oily. Towel dry it as there is no need to blow_dry your hair for the ponytail look. You might want to add a little bit of gel to give it a nice shiny look and to help keep those flyaway hairs under control.
If you have a man who isn't taking great care of his hair, or is in dire need of a makeover, it may be a great idea to mention to him which celebrity hairstyles you like. If he doesn't seem to be paying attention, you may want to accompany him to his barber appointment and quietly suggest it to his barber instead, that may work better.
