Hair Transplant: FUE vs FUT

Overview / Definition Hair transplantation is a surgical procedure that involves relocating hair follicles from a donor site to an area of thinning or balding scalp. It is primarily performed to address conditions such as androgenetic alopecia, although it can also be used for other types of hair loss. The two most common techniques are Follicular Unit Extraction (FUE) and Follicular Unit Transplantation (FUT). Epidemiology Hair loss affects a significant portion of the population, with approximately 50% of men and 40% of women experiencing some degree of hair thinning by the age of 50. The prevalence of androgenetic alopecia varies across different ethnicities: Men of Caucasian descent: 40-50% Men of African descent: 30-40% Men of Asian descent: 20-30% Pathophysiology / Mechanism Hair loss in androgenetic alopecia is primarily driven by genetic and hormonal factors. The key mechanism involves the effects of dihydrotestosterone (DHT), a potent androgen that causes miniaturization of hair follicles, leading to thinner hair and eventual follicular apoptosis. In FUE and FUT, hair follicles are harvested from areas resistant to DHT, commonly located at the back and sides of the scalp. Clinical Presentation Patients typically present with: Gradual thinning of hair on the scalp Receding hairline in men Widening part in women Physical examination often reveals characteristic patterns of hair loss consistent with the Norwood-Hamilton or Ludwig classifications. Diagnosis / Workup The diagnosis of hair loss is primarily clinical. A thorough history and physical examination are critical. Additional workup may include: Scalp examination to assess the extent of hair loss Blood tests to rule out systemic causes (e.g., thyroid function tests, iron studies) Scalp biopsy in atypical cases Treatment / Management Management options include both non-surgical and surgical interventions: Non-surgical: Minoxidil and finasteride are commonly used for medical management, particularly in ear
