Second Hair Transplantation

It might be necessary to undergo a second hair transplantation not only to optimise the result of the first one and to cover up the areas of the scalp that have developed hair loss at a later stage, but also to correct problems.

Current hair transplantation methods can offer you excellent cosmetic result at one treatment session. In this session, healthy hair follicles that are not hormone-dependent are transferred to the area showing hair thinning, so that to provide you with new hair and a permanent solution for your hair loss. The result is permanent as the growth of the transplanted follicular units is not affected by the effect of hormones (androgens), which are responsible for hair loss.

However, in the area showing hair thinning there are usually hormone-dependent hair follicles too, which may show atrophy and progressively become vellus hair, as they show no resistance to the androgens. Nevertheless, this is something that cannot be supported with certainty and cannot be predetermined, guessed or forecasted. Therefore, a second hair transplantation may be necessary in the future to achieve thicker appearance of hair at the area where the first hair transplantation was performed.

Patients are informed from the beginning for the type of hair loss they have. Following this, their personal medical file is put together, with all information collected through the trichoscopic examination, densitometry and laboratory tests in order to monitor the progress of hair loss with the use of comparative images, which allow us to make informed decisions about each patient’s treatment.

Given that the progress of alopecia may not stop with hair transplantation, there is some possibility for further hair thinning to occur, and this may necessitate a second transplant, to strengthen again hair density in the recipient area. A second hair transplantation may also be performed even in cases of stable hair thinning (especially in older people) so that to further improve hair thickness.

In both the above cases, and always given that the donor area’s hair growth is at a satisfactory level, during the first hair transplantation it is important to keep hair follicles, which can be used in case a second hair transplantation is necessary.

When is it necessary to have a second hair transplantation?

In certain cases it is necessary to have a second hair transplantation, not for the optimisation of the outcome of the first one and to cover up the new areas showing hair thinning, but for reparative purposes. If the medical scientific team who completed the first hair transplantation did not have the necessary expertise and did not design the transplantation appropriately, not taking into account natural hair loss progress, it is likely that scars or other wounds develop on the scalp, resulting in an unnatural frontal hair line or heterogeneous distribution of hair all over the scalp.

If this is the case, for the correction of the result special expertise in necessary, so that to design correctly the transplantation, which is more difficult that a first hair transplantation on the same person.
