Which of the following substances can be used during hair braiding?

Using topical agents like conditioners and oils during hair braiding is appropriate because these substances can enhance the hair's moisture, reduce friction, and improve manageability. Conditioners help in smoothing the hair cuticles, making it easier to braid without causing breakage or discomfort. Oils can provide additional slip, helping to prevent tangling and making the braiding process smoother.

On the other hand, chemical hair dyes, permanent wave solutions, and bleaching agents are not suitable for use during the braiding process. These substances involve more complex chemical reactions that can alter the structure of the hair and increase the risk of damage, which is not conducive to the protective styling intent of braiding. They can lead to hair becoming dry or brittle, contradictory to the goal of maintaining hair health during styling.
