Correct answer

Breaking and reforming the internal bonds of the hair to a new shape

A Breaking and reforming the internal bonds of the hair to a new shape
B Coating the surface only
C Adding temporary color
D Cutting the hair

Why this is the answer

Chemical texture services such as permanent waves and chemical relaxers create a permanent (chemical) change by breaking the hair's internal disulfide bonds, restructuring the hair, and then reforming those bonds in a new configuration — curl for a perm, or straightened for a relaxer. Because these are chemical changes within the cortex, they are long-lasting and only grow out or are cut off. Their strength and permanence are exactly why careful analysis, strand testing, and following directions are critical. This is core chemical-service theory.
