Concerned about head shape

I just noticed that my little ones head seems kind of odd shaped, he has long hair so I don't actually see the shape of his head unless I'm washing his hair, I don't think it was like this 4 days ago on his last bath day, he gets super dry skin if I give him baths more than every 3 to 4 days. His soft spot also seems pretty small, he's almost 6 months old is this normal?
