Figure 7: (a) Trichoscopy of congenital triangular alopecia shows carpet of vellous hairs (yellow arrows) with white dots and linear vessels (red arrow). (b) Trichoscopy of traction alopecia shows numerous vellous hairs that are emerging in single (yellow arrows) or in groups from a follicular ostium. Note the pinpoint white dots (red arrows) suggestive of early phase of disease. (c) Trichoscopy of traction alopecia in late phase shows vellus hairs (yellow arrows), broken hairs (red arrows), black dots (maroon arrows), and circle hair (green arrow). Note the white dots are replaced by patches (yellow stars). Brownish rings (blue arrows) are well appreciated. (d) Trichoscopy of trichoteiromania shows hairs with longitudinal splits resulting in broom hairs (yellow arrows). Lichenoid change is seen as brownish halo around follicles (red arrows). Note the conspicuous absence of black, yellow, or white dots. (e) Trichoscopy of lichen planopilaris shows loss of follicular ostia, perifollicular cast (yellow arrows), and pinpoint white dots. “Targetoid” pattern of blue-gray dots (red arrows) around follicular openings is well appreciated. (f) Trichoscopy of lichen planopilaris in late stage shows loss of follicular ostia, white patches (yellow stars) and blue-gray dots (red arrows). Note the pili torti seen as twisted hair shaft (yellow arrow). Linear vessels are indicative of topical steroid application. (g) Trichoscopy of lichen planopilaris in early stage shows multiple white dots (red arrows) on honeycomb pigmentation (yellow star) giving a “starry sky” pattern. Peripilar casts (yellow arrows) and subtle pinkish hue are well appreciated
