My husband has been talking about having a hair transplant. We weren't sure how much downtime he will need?

Hair transplant surgery is an outpatient procedure. You can resume normal activity next day. Unless your work is MMA fighting.  Most people take a few days off work. Most doctors advise no strenuous activity for a few weeks. 

Downtime after a hair transplant varies among individuals. If someone works from home, for example, normal work routines can occur within 24-48 hours. With the newer techniques such as follicular unit extraction, which I perform at my center, post-procedure discomfort is minimal. Also, this procedure leaves no linear scar. I usually recommend 4-7 days prior to returning to work -- there is swelling that occurs in some patients, along with a reddish appearance where the grafts are harvested and where they are implanted. The procedure is typically performed in a procedure room in an office or accredited facility. Rarely is hair transplantation performed in a hospital setting. Good luck!

Thanks for your question. The recovery depends on the type
of procedure and how much hair the patient wants transplanted. I recommend hair
transplant with NeoGraft® for most of my patients. This is a kind of follicular
unit extraction, or FUE, transplant that is aided by a handheld machine, which
removes hair follicles one at a time and then transplants them in another area.
The NeoGraft system takes much less time than a manual FUE transplant, usually
a few hours depending on the area, and it damages the scalp less. This makes
for a quicker recovery. Some of my patients have even returned to work the
following day, but 2 or 3 days off is more common. The procedure could be
performed wherever your surgeon generally does surgery. I recommend that you
and your husband look into NeoGraft and doctors in your area with a great deal
of experience and training with this system. Good luck!
