Women of African ancestry are most commonly affected. CCCA only affects the scalp.
CCCA may cause tenderness, pain, tingling, burning, “pins and needles” or itching of the scalp. Sometimes there are no symptoms other than an area of hair loss.
Crusts, pimples and scale may also be present in some cases and the scalp may feel soft or ‘boggy’ when touched. In most cases, there is a bald patch with shiny skin (scarring) seen in the centre of the scalp. Traction alopecia (loss of hair in areas of high tension) or hair breakage is also a feature.
The bald patch starts in the central part of the scalp (vertex or crown) and gradually expands outwards symmetrically (centrifugal). It may progress slowly (over decades) or rapidly (over years) resulting in patches of permanent hair loss (baldness).
