Figure 7. . Three-dimensional reconstructions of alopecia areata (a) and MAAs (b) demonstrating the loss of contact of the arrector pili muscle with the outer root sheath of the vellus hair follicle in MAA that is largely irreversible compared with maintenance of this contact of the arrector pili muscle with outer root sheath which is potentially completely reversible in alopecia area.
