Step-by-step explanation:
When areas of enlarged open follicles surrounded by clusters of red spots, indicating tinea capitis (ringworm) are observed, a cosmetologist should refer the client to a physician. Tinea capitis is a fungal infection that affects the scalp and requires medical treatment. Cleansing with a medicated shampoo or using antiseptic lotion may not effectively treat the infection, so it is important to seek professional medical advice.
