Experiment: Finally, it is not a bad idea to experiment once in a while. Change is the way of life. Why keep a constant hairstyle throughout your life? Why not try something different? However, proper research must be done before experiment especially if you need to go out of your house quite regularly.
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.
