Scar Treatment Advice?

Anyone have any thoughts on scar treatment?

I think the vitamin E thing has been debunked with research - any other wisdom out there? The one on my head is no big deal - it will be covered with hair eventually. But the one on my stomach is the one I may be able to minimize. It's what I would imagine a c-section scar might be like - but it's much smaller. Any thoughts? (Good thing I'm off the steroids now, or this one would be covered with hair eventually as well. And oh my God, steroids make you hungry! I think I have gained 20 pounds in one week.)
