The term that describes hair that has not been chemically altered is "natural hair." This designation refers to hair in its original state, meaning it has not undergone any treatments such as coloring, perming, or straightening that involve chemical products. Natural hair maintains its original texture, color, and health, which can be crucial for various hairstyling techniques and the application of products.

Other terms used for altered hair, like "dyed hair," "processed hair," and "treated hair," imply some form of chemical application or alteration. For example, dyed hair specifically refers to hair that has been colored, while processed hair encompasses a broader range of treatments, including perms and chemical straightening. Treated hair generally implies that the hair has undergone some sort of intervention, whether it is conditioning treatments, coloring, or styling processes. Thus, recognizing the distinction of "natural hair" is important in the context of barbering and hair care standards.
