Is there any way to make locs skinnier?

I have a few that are really fat. I'm only about four months in so I'm wonderin if this is permanent. Also I have tons and tons of loops. I like em. I think they're cute. I was just wondering if those were as well.

Cool thanks. How do I split them? There's like two that really are WAY too huge. I was thnking of combing those out and separating them but I don't know.

oh ok sweet! thanks :D
