DLE on the scalp is characterized by erythematous, scaly plaques with follicular plugging, and often occurs with DLE lesions elsewhere, unlike the more subtle, central thinning of CCCA.
This is a non-scarring alopecia due to miniaturization, distinguished by a widening of the central part line with retained follicles, whereas CCCA is a scarring process with loss of follicular openings.
FFA is a scarring alopecia characterized by a progressive recession of the frontal and temporal hairlines, often with loss of eyebrows, a different pattern than the vertex-centered loss of CCCA.
LPP is a scarring alopecia distinguished by its characteristic perifollicular erythema and scale, which is typically more prominent than in CCCA.
This form of hair loss is caused by chronic tension and is localized to the hairline where the tension is greatest, and is distinguished by a history of tight hairstyles.
