TLDR Trichoscopy is effective for diagnosing different types of non-scarring hair loss.

In a 2017 study of 200 patients with non-scarring alopecia, trichoscopy was proven to be an effective diagnostic tool. The study diagnosed 92 patients (46%) with androgenetic alopecia, 70 patients (35%) with alopecia areata, and 36 patients (18%) with telogen effluvium, while 2 patients had both androgenetic alopecia and alopecia areata. Trichoscopic signs included hair diameter diversity in androgenetic alopecia cases, with the peripilar sign being most common. Alopecia areata was characterized by black dots, broken hair, and yellow dots, while telogen effluvium was identified by the presence of one follicular hair unit and empty hair follicles. The study's conclusion emphasized the significant role of trichoscopy in accurately diagnosing different types of alopecia.

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present.
