Hair transplant evaluation starts with a physician identifying the extent of the hair loss a person has. After which, the doctor will then design the appropriate hairline for grafting, check the donor area (back of the head), and decide on the number or required grafts.
According to FueClinics.com, there are some issues that may arise in an evaluation such as the hair density and miniaturisation. These two factors dictate the viability of hair for transfer to pre-determine the effects post-op.
Changes in the Processing of Transplant Candidates
Before, when a patient falls out of the range of feasible transplant, physicians often discourage them with the low rate of success. But, with new methodologies in hair surgeries, this rarely happens anymore.
History of Hair Surgery
As early as the ‘90s, hair transplants have been among the fastest-growing trends in the medical market. Doctors popularly used a grafting method that transfers patches of hair to affected areas. But, this procedure gradually declined as the majority of the patients are unhappy with the results. The common deficiencies include unnatural-looking hair and long-term solution to hair loss.
The assessment for hair transplant patients starts with the doctor identifying the Norwood Classification. It consists of the following categories:
Class I: shows a juvenile hairline, which isn’t immediately a sign of total balding. Class I often rests on the loss of hair in the upper brow crease.
Class II: shows the maturity of a juvenile hairline to an adolescent one. The balding starts at this point with the temporal recession (1.5cm) minimum.
Class III: shows the most prevalent characteristic of hair loss, which is the deepening temporal recession.
Class IV: after Class II, the top of the head vertex follows the signs of hair loss. There are still solid bands of hair surrounding the top of the head, but a gaping patch is apparent.
Class V: the front and crown balding continue to further expose the scalp, resulting in an odd-looking hair arrangement.
Class VI: only the back and the side hairs remain.
Class VII: patients only have breadth and wreath of hair remaining.
With the improvements in technology today, it’s now possible to treat hair loss in all classes. There are also artificial grafting methods available that work for the legally bald.
