This study from North-East India analyzed 21 cases of frontal fibrosing alopecia, noting a high prevalence in post-menopausal women and distinct histological features such as perifollicular lymphocytic infiltrate and hydropic degeneration.

This report describes two patients with frontal fibrosing alopecia who developed acute hair loss on their limbs, revealing that the limb alopecia had similar histological features to scalp alopecia.
