Headgear-induced temporary pressure alopecia

Area of Science:

• Dermatology
• Orthodontics

Background:

• Pressure alopecia is localized, non-scarring hair loss from mechanical causes.
• Prolonged immobility, genetic, and immune factors can contribute.
• Extended mechanical trauma risks permanent follicle damage via hypoxia.

Purpose of the Study:

• To report a rare case of temporary pressure alopecia in a patient using orthodontic headgear.
• To highlight the psychosocial impact of hair loss in adolescents.

Main Methods:

• A 13-year-old boy used high-pull orthodontic headgear.
• Hair loss was observed in areas of headgear contact within four weeks.
• Diagnosis was confirmed by hair regrowth after discontinuing headgear.

Main Results:

• Localized hair loss occurred within four weeks of headgear use.
• The hair loss corresponded to the headgear's force delivery modules.
• Hair regrowth was observed after headgear removal.

Conclusions:

• Temporary pressure alopecia is a rare side effect of orthodontic headgear.
• Alopecia can significantly impact psychosocial well-being.
• Regular monitoring and avoiding excessive pressure are crucial for headgear patients.
