**12. Donor hair effluvium**

Hair effluvium is a relatively common occurrence in recipients, especially in females, whereas in donors, it is significantly less common. It usually presents within 6 weeks of surgery as temporary hair loss along the inferior and superior margins of linear wounds, or as diffuse hair loss in the case of FUE. Most likely, it is a consequence of anagen effluvium, in response to interrupted blood supply. Patients should be reassured that the problem spontaneously resolves within 3–4 months, but minoxidil can hasten hair regrowth.
