Figure 5:(a) Trichoscopy of androgenetic alopecia shows numerous miniaturized hairs (blue arrow), few terminal hairs (yellow arrow) and vellus hairs (red arrow). Note the single hair is emerging form a follicular opening and hair diameter heterogeneity. Honeycomb pigment pattern and white dots are well appreciated. (b) Trichoscopy of androgenetic alopecia in early stage shows peripilar brown halo (red arrows), numerous miniaturized hairs (blue arrow) and terminal hairs (yellow arrow). Note the single hair is emerging form a follicular opening. Honeycomb pigment pattern, diameter heterogeneity, and white dots are well appreciated. (c) Trichoscopy of androgenetic alopecia in advanced stage shows peripilar white halo (maroon arrows), numerous miniaturized hairs (blue arrow), and terminal hairs (yellow arrow). Note the honeycomb pigmentation, diameter diversity, and pinpoint white dots. (d) Schematic diagram shows eccrine white dots (i) and follicular white dots (ii). Eccrine white dot is surrounded by reticular pigment network whereas in follicular white dot is devoid of it (e) Trichoscopy of alopecia areata shows black dots (red arrows), coudability hairs (yellow arrows), short vellus hairs (blue arrows), and trichoptilosis (purple arrow). Note the exclamation mark hairs (green arrows) and tapered hairs (maroon arrows). (f) Trichoscopy of alopecia areata shows upright regrowing hair (red arrows) and yellow dots (blue arrows). Honeycomb pigment network is well appreciated. (g) Trichoscopy of alopecia areata shows pigtail hairs (yellow arrows), black dots (green arrows), coudability hairs (maroon arrow), exclamation mark hairs (blue arrows), and broken hairs (red arrows). Honeycomb pigment network is well appreciated. (h) Trichoscopy of alopecia areata shows yellow dots with central black dot (red arrows) and without dark dot (maroon arrows), few upright regrowing hairs (blue arrows), and short vellus (pigtail) hairs (green arrow). Note the polycyclic and irregular nature of yellow dots and honeycomb pigmentation
