Few therapeutic options exist, and there is currently no effective treatment except for hair transplantation. We report the case of an adolescent boy with CTA who was treated with 5% topical minoxidil solution. During therapy, the patient showed improvement in the form of the appearance of terminal hairs, which started to show after two months of treatment. After eight months of treatment, the affected area was fully covered with dense terminal hairs. The patient did not report any adverse reactions/side effects.Keywords: Congenital triangular alopecia, minoxidil, trichoscopy
