What must be assessed during a consultation before chemical services?

During a consultation before performing chemical services, it is essential to assess the hair type and the chemical history of the client's hair. Understanding the hair type—whether it is straight, wavy, curly, thick, or fine—helps determine the appropriate chemical products and techniques to use. Additionally, knowing the chemical history, including any past treatments such as coloring, perming, or relaxing, is crucial. This information helps predict how the hair will respond to new chemical processes and reduces the risk of damage or adverse reactions.

For example, hair that has been previously treated with chemicals may have a different texture or porosity than untreated hair, necessitating adjustments in the formulation or application method. Assessing hair type and chemical history ensures a safer and more effective service tailored to the individual client's needs.
