Frontal fibrosing alopecia (FFA) is considered a variant due to similar histological features.

Positive reactions in the European Baseline Series occurred in 26% of FFA patients, compared to 37% in the LPP patients and 56% in the control group. Common allergens included nickel and fragrance mix I, but their prevalence did not exceed rates in the general Israeli population. LPP\/FFA patients had fewer positive reactions to cosmetics, hair products, and sunscreens.
