Getting a hair restoration surgery is not only a matter of covering barren areas on the scalp with bald-resistant hairs. It is especially about getting the perfect framing and/or looking best with the newly-transplanted hairs. Not everyone however is qualified for a hair surgery. Individuals who do not qualify would most probably have unsuitable hair characteristics.
Each patient is evaluated during consultation and the hair characteristics are one of the major aspects which the physician would first look at.
Hair Color in Contrast to Skin Color
Color contrast between the skin and hair is one the major aspects to consider in achieving a desirable aesthetic outcome. The principle is that a lower contrast makes it easier for the physician to conduct the surgery. Therefore, the ideal candidates for grafting are patients with almost the same hair and skin color. Those with low-contrast colors will have fewer aesthetic problems, and which also contribute to the appearance of a good hair density.
The opposite goes for patients with high-contrast colors (i.e. light skin and dark hair). They would most likely suffer from a tufty appearance despite the use of minigrafts. But a natural, dense-appearing hairline can still be achieved although it will typically take more than three grafting sessions.
Hair Density
Hair density in the donor area determines how much hair will be available for transfer to the recipient area. Higher hair density means better supply of hair follicles for transfer compared to lower hair density. However, with high-contrast hair/skin color, higher hair density may most likely be unable to fully create a natural-looking result. Through the exclusive use of very small minigrafts, or even micrografts, patients with high hair density but with high-contrast hair/skin color can have a lesser risk of tufting within the recipient region.
Curl
The hair curl is an essential factor in coverage. If the hair is very curly, it provides best coverage because of the meshwork that it creates so that the light cannot penetrate to the scalp.
Calibre/Shaft Thickness
The hair calibre determines what physicians call the ‘hair mass’ which refers to the total effect of length times calibre. Those with thicker-calibre follicles may appear to have 50 - 100% more hair than those with thin, straight hair. Usually, it is only the light reflected throughout the scalp that makes the hair appear thin.
