Hair loss from pressure
Pressure alopecia refers to hair loss from prolonged positioning in a specific position. One of the most common causes of pressure alopecia occurs during prolonged surgeries (cardiovascular surgery, gynaecological surgery, abdominal surgery.)
Nowadays, it's pretty standard in the operating room for someone to be in charge of making sure the patient's head is turned frequently during surgery. If not, the tiny blood vessels get occluded and skin ulceration and hair loss can occur.
WHEN DOES PRESSURE ALOPECIA OCCUR AFTER SURGERY?
- Hair loss occurring a 7-14 days after the surgery from the middle back of the scalp usually indicates pressure alopecia.
- Patients may develop tenderness and crusting a few days before the hair loss.
- Fortunately for most - the hair loss is temporary and grows back in 1-2 months.
- However, for a small number of individuals the hair loss is permanent. Hair transplantation provides an option to restore density.
