Frontal fibrosing alopecia - Hair and Scalp
Alerts and Notices
Synopsis

There may be facial skin involvement (eg, perifollicular erythema or papules surrounding vellus hairs) in some cases, which may precede alopecia. Mucocutaneous lichen planus has occurred in up to 15% of cases.
There is a higher incidence of early menopause and history of hysterectomy without hormonal abnormalities on laboratory testing in affected women. Association with autoimmune conditions, such as vitiligo and hypothyroidism, has also been found. A recent study suggests that there is a possible link between sunscreen and moisturizer use and FFA, but the mechanism is unclear.
