What should a cosmetologist assess before performing any service?

Before performing any cosmetology service, it is essential for a cosmetologist to assess the client's medical history. This assessment is crucial because certain medical conditions, medications, or allergies can significantly affect the outcome of the service and the safety of the client. For example, some skin types may react negatively to specific products or treatments, and understanding a client's medical background allows the cosmetologist to make informed decisions that prioritize the client's health and well-being.

While assessing the client's skin type, hair texture, and hair color is indeed important to tailor the service to their individual needs, these factors are secondary to understanding any medical issues that might pose risks. Therefore, a comprehensive client consultation that includes a review of medical history is the foundational step in delivering safe and effective cosmetology services.
