Interlocks is a method of using a weaving technique to install and to maintain them. Whether they are interlocks, twisted locks, braidlocks, or sisterlocks. . Usually they are put in a certain grid or formation. This weaving pattern is what allows the locks to be very small. It also allows for the client to have more freedoms when it comes to styling and shampooing. I have found that many of my clients who work in the corporate work prefer these type of locking methods. They can hold a roller set and a crimp set very well. ​ With interlocking clients can do much of the maintenance at home. They can shampoo and style without coming into the salon s often. ​ With traditional locks or dreads, they are formed by twisting the hair into coils, are by letting them free form. Some may even add extensions.
