Dr. Richard Fitzpatrick: Some of them are just temporary. I mean, there are immunological reasons, where you get patchy hair loss and that is called Alopecia areata, and that can be a big widespread problem, where you lose all of the hair on your body. Or, it can be isolated to just small stops. When it is isolated, generally it heals fast. It may last six months or so.

There is also hair loss for medical reasons from anemia, thyroid disease, from scalp inflammation, Suborrheic dermatitis, Eczema, Psoriasis. You can also lose hair from scalp diseases that cause scarring. All of those conditions that I have just listed, generally are not candidates for hair transplantation. And we want to rule those out, before we start hair transplantation, because if you try to transplant when there is a medical reason, then the transplanted hair is going to be subject to loss as well.

So, it’s only in scarring or in genetic pattern type hair loss that hair transplantation is valuable.
