Hey there! From my experience, I would recommend holding off on wearing a hat for at least the first two weeks after an FUE hair transplant. It's crucial to allow your scalp to properly heal during this initial period to minimize any potential risks of infection or follicle damage.
I know it can be tough to go without a hat, especially if you're self-conscious about the procedure, but it's a small sacrifice for the long-term results you're aiming for. Trust me, the patience pays off in the end! Just make sure to follow your doctor's post-op instructions closely and you'll be back to rocking your favorite hat in no time. Hang in there!
