Traumatic Alopecia
Traumatic alopecia frequently appears on the margins of the scalp and sometimes shows irregular patchy hair loss to the crown area. There will be breakage to these area and also short re-growing hairs. It is caused by excessive chemical, thermal or physical trauma as well as scratching the scalp. Traumatic alopecia is frequently seen on Afro-type hair when subjected to any or all of the above hairstyling methods over long periods.
