to brush or not to brush?

I've been having a huge internal debate the last few months as to whether or not I should try to brush out my dreads and start over... but I don't know if it would be different the second go around. I am at almost one year. My biggest dislike is that a lot of my dreads are A LOT thicker on the bottom than at the top, pretty uneven. They shrank up a lot on the bottoms and the top halves just kind of dreaded straight (how I wish all of my hair would have dreaded) With more time will they eventually round out a little more? Idk. I guess any comments would help. I have some pictures uploaded in my photos. Thanks.

have patience honey, they are doing exactly what they should be. love them they will get better!

My dreads are still thicker on the bottom because a whole lot of hair shrank into about 6 inches of dread. That is just how it is. Don't worry it will round out. It just takes time.
