TLDR Less than a quarter of alopecia areata cases were unusual forms or had paradoxical regrowth.
The study analyzed 488 cases of alopecia areata (AA) from a Trichology Unit over an 11-year period and found that 114 cases (23.36%) presented with unusual forms or paradoxical regrowth. The most frequent atypical form was sisaipho type (7.37%), with other variants including AA for black and blonde hair (5.32%), atypical diffuse forms (4.30%), AA androgenetic type (3.89%), and AA rectangular occipital (0.68%). Additionally, there were nine cases (1.84%) of paradoxical regrowth. The research highlighted that less than a quarter of the AA cases were atypical, but also acknowledged the possibility of selection bias due to the specialized nature of the unit.
