TLDR Congenital triangular alopecia is a hair loss condition present from birth or early childhood with no effective treatment needed.
Congenital triangular alopecia (CTA), also known as temporal triangular alopecia, is a rare, non-progressive, non-scarring type of hair loss that can be present at birth or develop in early childhood. It typically appears as a triangular, oval, or lancet-shaped patch of alopecia on the frontotemporal scalp. Diagnosis is aided by dermoscopy, which reveals normal follicular openings with vellus hairs. There is no effective treatment, but options include topical minoxidil, surgical excision, and hair transplantation. In a reported case, a 23-year-old male showed new vellus hair growth after 3 months of minoxidil treatment. The condition is often misdiagnosed as other types of alopecia, but proper diagnosis can prevent unnecessary treatments.
