alopecia areata pressure-induced alopecia extraoral orthodontic appliances corticosteroid injections hair loss steroid injections

TLDR Orthodontic appliances can cause hair loss due to pressure.

The document reported the development of alopecia areata in two patients due to pressure from orthodontic headgear. In one case, hair loss began 2 weeks after starting the appliance, while the other patient noticed patchy alopecia 2 to 3 weeks after increasing the pressure and duration of use. One patient also developed alopecia areata in areas unrelated to pressure. Hair regrowth occurred in about 5 months after relieving the pressure, with one patient receiving corticosteroid injections and the other receiving no medical therapy. The study concluded that local pressure from orthodontic appliances could trigger alopecia areata.
