Pressure alopecia is a form of hair loss that occurs as a result of sustained pressure on the scalp. This condition is most commonly seen in individuals who have been bedridden for extended periods of time, such as those recovering from surgery or suffering from severe illness.

Causes

Pressure alopecia is caused by prolonged pressure on the scalp, which can lead to damage to the hair follicles. This can occur in a variety of situations, including:

• Long-term bed rest
• Wearing tight headgear for extended periods
• Certain hairstyles that pull on the hair

Symptoms

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

Treatment for pressure alopecia primarily involves removing the source of pressure on the scalp. This may involve changing hairstyles, adjusting headgear, or modifying sleeping positions. In some cases, medications may be used to promote hair growth and reduce inflammation.

Prevention

Prevention of pressure alopecia involves avoiding prolonged pressure on the scalp. This can be achieved by:

• Regularly changing positions during long periods of bed rest
• Avoiding hairstyles that pull on the hair
• Wearing loose-fitting headgear
