Before performing a chemical service, it is essential to check the client's medical history to ensure their safety and well-being. This information can reveal any allergies, skin sensitivities, or medical conditions that could potentially lead to adverse reactions during or after the chemical treatment. Understanding a client's medical background allows the cosmetologist to make informed decisions about the suitability of the chemical service for that particular client and to take any necessary precautions.

While aspects such as hair type, current hair color, and personal preferences are important in the overall hair service, they do not directly address potential health risks associated with chemical treatments. For example, certain medical conditions or medications can contraindicate the use of certain chemicals, making the review of medical history crucial. Prioritizing client safety by reviewing medical history helps prevent complications such as burns, allergic reactions, or other health-related issues that can arise from chemical processes.
