I doubt it. You have a widow's peak which is often a sign of hair vigor with hair loss being confined to the temples but if it gets worse then seek treatment. Right now, I would say get Nizoral and Selsun Blue and use them to lessen inflammation. I can't see in front of your ears but many or most guys lose hair there and never even realize it because on its own, it might not be cosmetically significant but if you have both then yes, it's time to nip this in the bud as they say before it worsens. You still have time to restore but don't wait.
Also if you notice all of a sudden that your hair looks less and less good worn long, then that is a definite sign of possible hair loss.
