CCCA usually begins at the<unk>  (sagittal) midline of the scalp. It is symmetric and exhibits scarring as the name suggests. It involves solely the top of the scalp or may progress to Hamilton–Norwood scale Type VI or VII. Early symptoms may include pruritus, dysesthesias and tenderness. On examination the skin is thin with few follicular ostia and later in the disease the scalp may appear shiny.
