Pathological loss of hair due to internal disease:

Lots of internal diseases, hormone disorders and auto-immune diseases manifest itself with hair loss. In this case, a hair transplant cannot be performed. In these cases, it is advisable to cure first the main sickness. The hair follicles are almost always never lost and, expectedly, they will grow again after the main illness has been successfully treated (please refer to Forms of hair loss & causes). If you are affected with such illness, consult with the doctor, who is treating your main illness. At the same refer your problem to a dermatologis

 

 

Too few donor hair: 

Persons with too few donor hair, for example, those falling under the category Norwood class 7 (NW7) with a back of the head having only a few remaining rest hair and without enough strong body hair (which can be used as body grafts) are not legible for a hair transplant with dense hairline. In the aforementioned cases, there is not enough donor grafts that can be gathered to reach an acceptable result afterwards.

However, there is a possible for a NW7 baldness can be converted into NW6 or even to NW5.  Such a step is, indeed, only a small step, but a lot of males may consider it as a great improvement of their case. It is also possible to form a thoroughly age-relevant natural-looking hairline in a patient having NW7, provided that it is sparsely formed. There is a form observed in untreated hair loss, wherein the baldness of the upper head and the tonsure is well-expressed and yet with a hairline still in existence no matter how sparse it may be. Such a naturally-formed thin hair line usually looks much better than a complete NW7 condition.

Unfavourable prognosis:

Men with an unfavourable prognosis (for example, when several members of the family have reached a higher Norwood status within a short period of time or when this is already reached in younger years) are not legible for a hair transplant. In these cases of a fast-advancing deterioration of the patient's hair condition, the patient would be not contented with the FUE results in the long run. Therefore, it is much better, if one tries to stop the loss of hair or its progression through application of medicines. If this works and if the loss of hair does not progress for a certain period of time, then FUE can be considered. However, this calls for some patience on the side of the patient.

Example:
A patient is confronted with an intensively rapid case of hair loss in his early 20's. According to the Norwood scale, his is a condition similar to that of NW3. His older brother's status is already in NW5. His grandfathers on both sides have NW7. At the present moment, the patient takes a 5-alpha- Reductase- inhibitor (for example, Propecia®), which greatly hinders the progression of his hair loss. Five year later, the same patient's status still coincides to NW3. His brother's status, who has had no medication at all, has reached NW6 in the meantime. In such case, the patient can consider having a FUE hair transplant. If his hair status practically is no changed even after 10 years waiting, he now can make a FUE with good confidence, certainly as long as he further takes a 5-alpha- Reductase- inhibitor also after his FUE.
