Final answer:
D) performing a metallic salts test
During the consultation for a chemical relaxer, risks are discussed, and the suitability of the treatment is confirmed. The client's dislikes about their current hair are noted to better address their needs. However, performing a metallic salts test is not part of this consultation as it is more relevant to hair coloring history.
Step-by-step explanation:
The process you are referring to falls under the category of cosmetology, particularly hair treatment services. During a consultation for a chemical relaxer, several steps are taken to ensure the safety and satisfaction of the client. These steps include discussing risks associated with relaxers, confirming if a relaxer is the best treatment for the client's hair, and asking what the client dislikes about their hair to tailor the treatment to their needs.
However, performing a metallic salts test is not typically part of the consultation for a chemical relaxer. Metallic salts tests are conducted when there is a suspicion of metallic compounds present in the hair, which can react unfavorably with the chemicals in the relaxer. The presence of these salts is usually considered when the client has previously used certain hair color treatments, not relaxers.
