It is in the right spots, but doesn't look like over grooming to me.
This is Simon, he began over grooming at the rescue just before we got him.
This was taken a couple weeks after we got him. Two patches turned into one large patch. Then he started 2 new patches above his eyes where the patches seem to be on yours.
This is his regrowth after a few Rogaine treatments lol jus kidding. About 3 weeks of regrowth, his hair matches the rest of him. Maybe a little greyer as he still has some brown on the rest of his fur but the texture is the same.
So my guess is yours is not over grooming! maybe a skin condition or something genetic??
