Which of the following scalp or hair conditions would generally prohibit (contraindicate) a salon service?

Reviewed by Jordan Morley, Editorial Lead at 247SimpleTests. Written by the 247SimpleTests Editorial Team from the official source material cited on every question.

Correct answer

An infectious or inflamed condition, such as an active fungal infection or open sores

A Healthy hair
B An infectious or inflamed condition, such as an active fungal infection or open sores
C Slightly dry ends
D Normal oiliness

Why this is the answer

A cosmetologist should not perform a service when the client has an infectious, inflamed, or broken-skin condition of the scalp or skin — such as an active fungal infection (like ringworm), severe inflammation, open sores, or signs of infestation — because the service could spread infection or worsen the condition. In such cases, the client should be referred to a physician. Recognizing contraindications protects the client, the professional, and other clients. Distinguishing normal conditions from those that prohibit service is a key exam and safety skill.
