What is the term for a client who presents with a red ring and white, itchy scales on the scalp?

The term that describes a client with a red ring and white, itchy scales on the scalp is ringworm, which is a common fungal infection known as tinea capitis when it affects the scalp. This condition is characterized by circular patches of red, scaly skin that can sometimes look like a ring, hence the name "ringworm." It's caused by dermatophytes, which are fungi that thrive on keratin found in hair, skin, and nails.

Recognizing ringworm is crucial in the salon environment because it is contagious. Understanding the distinctive appearance—such as the presence of red rings and white scales—helps professionals to correctly identify the condition and take the necessary precautions to prevent spreading the infection to other clients.

Other skin conditions listed, such as psoriasis, eczema, and dermatitis, have different characteristics and causes. Psoriasis typically presents as raised, red patches covered with thick silvery scales, while eczema often appears dry and flaky with various patterns of inflammation. Dermatitis can encompass a wide range of skin reactions, which may not necessarily present with the characteristic ring shape seen in ringworm. Identifying these differences aids in appropriate assessment and referral for treatment.
