Focal Asymptomatic Hair Loss in an Adolescent: A Case Report

The case report described a 13-year-old male with temporal triangular alopecia (TTA), a rare, non-scarring form of hair loss that usually appears in childhood. The patient's condition was characterized by asymptomatic, focal hair loss on the right frontotemporal scalp, which was non-progressive and had a poor chance of hair regrowth. TTA was identified through clinical examination and patient history, distinguishing it from other types of non-scarring alopecia, such as alopecia areata, due to the absence of symptoms like hair pull positivity and fractured hairs. The report highlighted the need for recognizing TTA in children to reassure patients and their families about its benign and stable nature. While treatment is often not required, options such as topical minoxidil, hair transplantation, or surgical excision exist for cosmetic purposes.
