|This method is the least-likely method to unravel and need re-twisting. Locs that are interlocked usually hold for longer periods of time even throughout the washing process which makes it perfect for hair that is naturally straighter, or is still ridding itself of chemical relaxers.
||For interlocking, you will require a tool such as a crochet needle or latch-hook (not more than $10) although I have seen some create their own hooks out of paperclips or random pieces of wire. Some people may be able to do this method themselves. However, I think it would be a difficult process, which means you will need to have a friend or hair dresser on hand. Because the loc will be fairly tight at the root, this method can also be uncomfortable, and cause tension at the root which is not good for your hair and can cause breakage. If you decide to do it yourself, beware of doing it incorrectly which will cause holes in your locs in the long run.
