  Fig. 1 The measurement of diameter along suprabulbar and mid-shaft level in hair shafts. (A) Bulbar portion of a hair and (B) mid-shaft portion of the same hair in a patient with acute TE. (C) Bulbar portion of a hair and (D) mid-shaft portion of the same hair in a healthy control. Significant thinning of the suprabulbar area of a hair is observed compared to the mid-shaft portion of a hair in acute TE (61.36 µm vs. 83.40 µm). In contrast, control shows similar thickness between the suprabulbar and mid-shaft portions of a hair (84.69 µm vs. 85.23 µm) (under 400× magnification). (E) The suprabulbar/mid-shaft level diameter ratios of hair in acute/chronic TE and controls. The diameters were measured across the suprabulbar and mid-shaft levels of hairs (about distances of 3–5 cm from the proximal ends of hairs) under a microscope. The ratio of the diameter along the suprabulbar level to the mid-shaft level in hair shafts was significantly decreased in acute TE group (0.84±0.05) compared with chronic TE (0.89±0.07, p=0.004) and controls (0.94±0.07; p<0.001) in ANOVA (p=0.003), Tukey's post-hoc test. TE, telogen effluvium.
