The eyebrows may be lost for various reasons, including the thyroid diseases and other systemic diseases, such as alopecia areata, burns, tattoos, infections, repeated depilation, congenital weakness in their growth, and a genetic tendency of the eyebrows to thin, or even disappear, over time.

Eyebrow restorations are similar to the hair transplantation procedures performed on the scalp, meaning that, in the case of suitable candidates, transplanted hair is permanent.

However, since the eyebrows have their own unique properties, eyebrow transplantations differ from hair transplantations at various important points.

The most important aspect of eyebrow transplantation is to very closely follow the direction of the natural hair.

The hair receiving areas should be prepared with a very fine (diameter wise) needle guide which will literally apply, along the surface of the skin, as the implantation points shall be determined, a practice which shall ensure that the hair is located, as long as the possibly, at the same level as the skin surface, as new hairs grow.

Another important part of eyebrow restoration is that only individual hair follicles can be used. Since, of course, the scalp consists of 1 to 4 hairs per hair follicle, hairs obtained from this area must be subdivided into 1-hair grafts, using a microscope.

From a technical point of view, eyebrow transplantation is not actually a transplantation of hair follicular units, but it is rather a highly sophisticated form of micro-transplantation.

Moreover, when the patient’s hair is wavy or curly, it is especially important to rotate the direction of this hair, so that the curve of the hair to be implanted follows the natural curve of the eyebrows.

1. Use of a single (and single only) hair in transplantation rather than multiple hair follicle grafts.
2. The hair should be rotated to follow the natural curve of the forehead and the extension of the eyebrow.
3. Transplanted hair should be implanted as flat as possible (parallel) to the skin surface.
4. Transplanted hair should be placed in such a way as to resemble to the changes in the natural direction of the hair in the various parts of the brow, namely with the upper eyebrow hairs to project slightly outwards and slightly downwards and the lower ones (hairs at the end of the brow) projecting outward and slightly upwards, in order to create the mutual ridge which offers the naturalness of the eyebrows.

Although eyebrow transplantation is a safe and aesthetically elegant process, there are a few things to look for before one subjected to this kind of hair restoration.

As with hair transplantations on the scalp, transplanted eyebrows shall continue to grow and should therefore be cut periodically.

Apart from the fact that this may be a minor nuisance in general, cutting off the particular hair leaves a final appearance, after the cutting, which is not as delicate as it happens with the smooth edges on the end of the intact hair of the normal brow. During the healing process, all incisions tend to converge.

When this occurs in the graft receiving regions, there is a possibility that their flat orientation may slightly change, and sometimes this results for the eyebrows in those areas being slightly more upright than someone would like.

Unlike hair transplantations, where the transplanted hair is taken from another part of the scalp and fit perfectly, when it comes to eyebrow transplantations, the grafts are taken from a part of the body other than the eyebrows and they will therefore have slightly different characteristics, both in terms of growth and appearance.

If different, then, over time, these transplanted hairs shall slowly begin to approach the developmental pathway and the characteristics of the existing eyebrow hair.

The appearance of eyebrow transplantations shall mature and be perfected over a year or so.
