Answer:
Well there are many ways to have a great rocking hair style ..... put it all depends on what length your hair is
short hair - Selena Gomez has a great rock style for short hair . If you add layers and angles it would make it look very punk-ish !
Long hair- Demi lavoto has a great look but i would just do layers and no angles for this style cause it would be too much to look at for long hair ..
next time you go to the hair salon bring a photo to your stylist and show her what you would like and remember those to actresses hair styles..
