Which condition might prohibit a stylist from performing a service?

Active scalp infections are a significant concern in the cosmetology field because they pose serious health risks to both the client and the stylist. When a stylist encounters a client with an active scalp infection, such as ringworm, psoriasis, or other contagious conditions, it is crucial that they refrain from providing hair services. This is to prevent the potential spread of infection to other clients, as well as to safeguard their own health.

Addressing scalp infections typically requires medical intervention and treatment, which makes it inappropriate for a cosmetologist to perform any hair treatments until the infection has been resolved. This approach not only adheres to health and safety regulations but also demonstrates a commitment to client care and wellbeing.

Other conditions, such as dry hair, curly hair, and split ends, do not impair a stylist's ability to provide services. While these conditions may affect the type of treatment or products recommended, they do not represent a health risk or contraindication for performing hair services. In contrast, active scalp infections require caution and professional judgment, making them a valid reason for postponing service.
