What should be done before applying a chemical treatment?

Informing the client of potential effects is crucial before applying a chemical treatment because it ensures that the client is fully aware of what to expect. This includes discussing the treatment process, possible outcomes, any side effects, and aftercare required to maintain the results. Keeping the client informed fosters trust and allows them to make educated decisions regarding their hair. This step is part of providing a professional and safe service, highlighting the importance of communication in the beauty industry.

While other options may have their own importance in different contexts, they do not directly address the immediate needs and protections required prior to chemical treatments. Cleaning the salon contributes to hygiene but is not specifically tied to the treatment process. Choosing the least expensive option does not prioritize the client’s needs or safety. Performing a haircut first may be relevant depending on the treatment but does not address the necessary precautions of informing the client about potential outcomes of the chemical treatment itself.
