What is an essential topic to discuss during a consultation before performing a perm?

Discussing hair history and health is crucial during a consultation before performing a perm because it directly influences the outcome of the treatment and the overall health of the client's hair. Understanding the client's previous hair care practices, including any past chemical treatments, color processes, or use of heat styling tools, allows the stylist to assess the condition of the hair. If the hair is damaged or overly processed, it may not withstand the perming process, which can lead to breakage or unsatisfactory results.

Additionally, knowing the hair's health status can help the stylist determine the best perm techniques and products to use, ensuring that the treatment is tailored to the individual's needs. This conversation also establishes trust and ensures that the client has realistic expectations about the process and results. Ignoring this essential topic could result in potential hair damage or unsatisfactory outcomes, making it a foundational aspect of any perm consultation.
