Final answer:
If an incorrect braiding technique is used, the hair shaft can become stressed and damaged.
Step-by-step explanation:
If an incorrect braiding technique is used, the hair shaft can become stressed. The hair shaft is the part of the hair that is visible outside of the scalp. It is made up of three layers: the cuticle, cortex, and medulla. When the hair shaft is subjected to excessive or improper tension during braiding, it can lead to breakage, thinning, and overall damage to the hair.
