Nowadays, the best method to open these micro channels is through the use of blades in sapphire. They are sharp, smooth, resistant and have sizes ranging from 1.0 mm. to 1.5 mm. With these sapphire scales it is possible to cut micro-channels of the same size as the hair follicles, further creating them by inserting the follicles closer together.
Some hair transplant centers say they can transplant by inserting 65 to 70 follicles per square centimeter, advertising a more dense and natural result. This is not possible with the use of either sapphire or steel scalpels.
In order to achieve a natural looking result, hair follicles must be implanted while considering the patient’s hair growth features. If the follicles were implanted in amounts of 65 to 70 per square centimeter, a natural result would not be expectable, as it would not be possible to make so many incisions while minding the right direction. This way, hair growth would not have a natural appearance due to its density.
The angle of natural hair growth ranges from 40 to 45 degrees. Considering the previously expressed density, hair follicles should be implanted perpendicular to the scalp, causing something called “doll effect”, a very unnatural appearance.
