The easiest hair style changes for an idol to do is to go from wavy to straight or vice versa -- and man, they look good with both, hands down!  However, there is always a preference for one or the other depending on the face shape or the general vibe.  Some guys look completely adorable with the wavy hair look for a deadly double combo of labradoodle looks and puppy eyes.  Some guys appear classier, but there is no doubt the wavy look accentuates their sweet gaze.  On the other hand, some people consider the straight hair a classier, manlier look.

Check out these five male idols below and decide for yourself which look you prefer on them!
