Which technique is NOT included in hair braiding?

The technique that is not included in hair braiding is chemical hair straightening. Hair braiding typically involves methods that manipulate the natural texture and form of the hair, such as twisting, weaving, and locking. These techniques maintain the hair's texture and style it without the use of chemicals.

Chemical hair straightening, on the other hand, is a process that alters the hair's structure to make it straight. This method involves applying chemicals to break down the hair's natural curls and waves, which does not align with the principles of braiding. Braiding focuses on interlacing strands of hair together, allowing for a variety of styles while keeping the integrity of the hair's natural form. Therefore, chemical hair straightening is distinctly separate from traditional hair braiding techniques.
