Q: Can shock loss be eliminated by using special surgical techniques? — R.P., Short Hills, NJ

A: Although there have been no scientific studies proving this, shock hair loss can most likely be minimized by keeping the recipient sites parallel to the hair follicles, by not creating a transplanted density too great in areas of existing hair, and by using minimal epinephrine (adrenaline) in the anesthetic. We implement all of these techniques. Finasteride may also decrease shock hair loss, or at least help any (miniaturized) hair that is lost to re-grow. That said, some shock hair loss from a hair transplant is unavoidable regardless of the technique as it is a normal physiologic response to stress.

Q: I am about 3 months post-op after my hair restoration procedure. I have noticed some hair shedding in the frontal part of my scalp. I have continued both Propecia and Minoxidil. Is there anything I can do and should I be concerned? — M.B., Chicago, IL

A: Shedding of some of the patient’s existing hair in, and around, the area of a hair transplant is a relatively common occurrence after a hair transplant and should not be a cause of concern. The mechanism appears to be a normal response of the body to the stress of the hair restoration surgery -– i.e., site creation, adrenaline in the anesthetic etc. Some doctors claim that their hair transplant techniques are so “impeccable” that their patients do not experience shedding. This is a false claim. Although using very small recipient sites and limiting the use of epinephrine may mitigate shedding somewhat, shedding is a normal part of the hair transplant process and the risk is unavoidable.

It appears that a person’s normal, non-miniaturized hair, as well as transplanted hair, is somewhat less subject to shedding than hair that is actively miniaturizing (thinning from the effects of DHT). In addition, if transplanted hair or non-miniaturized hair is shed, it will grow back. If miniaturized hair is lost, however, it may or may not return.

Since both finasteride and minoxidil reverse the miniaturization process, they should decrease the amount of hair at risk from shedding after hair transplant surgery. This has been our clinical experience, but it is important to note that as yet there have been no scientific studies to support this view.

At this time there is not much you can do except to be patient and wait for the newly transplanted hair to grow in and for the shed hair to return. Of course, make sure you continue to take finasteride and/or minoxidil if the doctor has prescribed it for you.

Q: I have read about something called “tumescent anesthesia” but didn’t understand what it is. What exactly is it? — S.S., Hoboken, N.J.

A: Tumescent techniques were first popularized in liposuction surgery where large quantities of fluid containing adrenalin were injected into the person’s fat layer to decrease bleeding before the fat was literally sucked out of the body. Bleeding was minimized because the epinephrine (adrenaline) constricted blood vessels and the fluid compressed the blood flow in the smallest blood vessels called capillaries.

The technique allowed small liposuction procedures to be performed safely as an out-patient procedure. In surgical hair restoration, low concentrations of anesthetic fluid and adrenaline are injected into the fat layer in the back of the scalp.

In a hair transplant, besides decreasing the bleeding, the fluid makes the skin more rigid so that the incision can be more easily made without cutting hair follicles. It also helps the doctor avoid damage to the deeper blood vessels and nerves in the scalp.
