For a standard Sapphire FUE or DHI hair transplant in Istanbul, most international patients stay for 3 to 4 days (2 to 3 nights). Day 1 involves airport pick-up, blood tests, and your in-person hairline design and consultation with the surgeon. Day 2 is the procedure itself, which typically takes 6 to 8 hours under local anesthesia. Day 3 is a rest day or bandage check, and on Day 4 the clinic performs your first medical hair wash, provides your aftercare kit (special shampoo, foam, and medications), and transfers you back to the airport.
