Figure 3: Mean number of mast cells (+standard error mean) per highpower field in telogen effluvium, alopecia areata, androgenic alopecia and normal (CONTROL) scalp biopsies. Tukey post hoc analysis showed the mean mast cell count for the telogen effluvium group to be significantly larger than androgenic alopecia (Giemsa, *P = 0.002; Tryptase, *P = 0.006) and CONTROL (Giemsa and Tryptase, *P < 0.001) and also showed the mean mast cell count for telogen effluvium to be significantly larger than alopecia areata (Giemsa and Tryptase, **P < 0.001)
