Saiyan Hair
After looking at countless pictures of saiyans I have discovered something interesting. The hair of a supersaiyan can be drawn more than one way.
To the right is the first way to draw supersaiyan hair --- >
                                                                                  
< --- to the left is the second way to draw supersaiyan hair
                     
Neither way is considered the wrong way but I believe more fans recognize supersaiyans to have more of a large clump of hair rather than strand by strand.
             
When they're hair changed:
Vegeta: Dbz (Cell saga)
Goku: (Never changed)
Trunks: (Was always drawn the second way)
Goten: (Was always drawn the second way)
Gohan: Changed once transforming to the supersaiyan level two form in the cell saga.
Gotenks: (Always drawn the second way)
Gogeta: (Always drawn the first way)
Vegetto: (Always drawn the second way)
Pan: (Never went supersaiyan in the first place.)
