What are dry, sulfur-yellow, cup-like crusts on the scalp called?

The correct term for dry, sulfur-yellow, cup-like crusts on the scalp is "scutula." This condition is associated with a fungal infection known as tinea capitis, which typically affects the hair and scalp, particularly in children. Scutula form as a result of the body's immune response to the fungus, leading to the accumulation of dead skin cells, oils, and other debris that clump together in a distinctive way.

Understanding the nature of scutula can aid in identifying the related complications and treatment options necessary for effective management. This terminology is essential for those studying cosmetology and dermatology because it highlights the importance of recognizing various scalp conditions and their implications for hair health.
