Yes, you can simply cut them off. However, taking the dreadlocks out without cutting your hair is not always possible. The younger the dreads are the easier they are to undo but the older and more mature they are the more difficult they are to remove. The method used for installation and maintenance also makes a big difference. Dreadlocks that are interlocked, especially with straighter hair, is often the easiest to remove. Dreads that are young and twisted would be fairly easy to remove as well. The hardest to remove is dreadlocks that are done with the crochet method, which is one of the only downsides of the method.
