The answer is NO. When done properly interlocking actually strengthens your loc base. It pulls in all those loose flyaway hairs that don’t have a loc home into place. This technique helps to keep locs the same size. It also eliminates that feared “fro-locs” look.
When interlocking is used for maintenance, it tightens the new hair growth to the scalp and locks it over time. Interlocks can be done with fingers, a specialized tool (interlocking tool), or a latch hook. A common way to interlock dreads is to use a 4 point interlocking pattern, in which the ends are pulled through the root in all four angels.
