Pressure alopecia
Pressure Alopecia
Pressure alopecia (pronunciation: /ˈprɛʃər ælˈoʊpiːʃə/) is a form of hair loss that occurs as a result of sustained pressure on a specific area of the head. This condition is most commonly seen in individuals who have been bedridden for extended periods of time or who wear tight headgear regularly.
Etymology
The term "pressure alopecia" is derived from the Latin word pressura meaning "pressure", and the Greek word alopex meaning "fox", which is used metaphorically to refer to "hair loss" as foxes are known to lose their hair due to mange.
Causes
Pressure alopecia is typically caused by prolonged pressure on the scalp. This can occur due to a variety of reasons, including:
- Long-term bed rest or immobility
- Regular use of tight headgear such as helmets or turbans
- Certain surgical procedures that require the head to be immobilized for extended periods
Symptoms
The primary symptom of pressure alopecia is hair loss in a specific area of the scalp. This hair loss is typically patchy and localized to the area that has been under pressure. Other symptoms may include:
- Scalp tenderness
- Redness or inflammation of the scalp
- Changes in the texture of the hair or scalp
Treatment
Treatment for pressure alopecia primarily involves removing the source of pressure on the scalp. This may involve changing headgear, adjusting sleeping positions, or using specialized pillows or cushions to redistribute pressure. In some cases, hair transplantation may be considered if hair loss is severe and does not improve with conservative measures.
