Asymetry in Oblique Portion of Abs?

I have got the most irritating asymmetry in my obliques…on the left when I flex them you can clearly see a couple different heads (is that the right word) but on the right side barely even 1.

It’s really irritating me and I was wondering if anyone else has this? I’m at school right now so I can’t post pictures, but will when I get home. In the meantime, anyone have experience with this, and how did you correct it??
