Although numerous haircuts could be used nowadays but it is better to choose a haircut according to the shape of your face. Likewise, if you have a triangle face shape then a quiff haircut should be your prime choice. It is very popular among celebs. Indeed, David Beckham and Robert Pattinson look very handsome in this haircut.
