- Long-term bed rest
- Wearing tight headgear for extended periods
- Certain hairstyles that pull on the hair
Symptoms[edit]
The primary symptom of pressure alopecia is hair loss in the area of the scalp that has been subjected to pressure. This hair loss can be gradual or sudden, depending on the amount of pressure and the length of time it has been applied. Other symptoms may include:
- Redness or inflammation of the scalp
- Tenderness or pain in the affected area
- Changes in the texture or color of the hair
Treatment[edit]
