The pigment cells in your left arm are still producing melanin, whereas the ones in your right arm (and on your head) are no longer doing so. It might be because your left arm has a slightly better blood supply than your right arm does (through being closer to your heart) but it's equally likely to be 'just one of those things' that nobody can really explain.
