In the hair transplant field density is a frequently used word and is something that many hair transplant doctors strive to achieve, whenever possible. This is because high density is strongly desired by many prospective hair transplant clients, because higher density will result in fuller hair, which will contribute to a more youthful look. Hair density refers to how closely together the hairs are placed, and is usually measured in numbers of follicular units per square centimeter of the scalp.
When it comes to a hair transplant, having high density may not always be possible, especially if there are not enough hairs to transplant. This is where density and donor supply go hand in hand. Donor supply refers to how much hair is available to transplant, some clients have a good amount, while other clients have much less. A hair transplant doctor can always try to achieve high density, but if there is not plenty of donor hairs, there is only so much that can be done.
When there is not an abundance of donor hairs, the doctor can try to strategically place hair follicles as to give an illusion of more hair. But someone with a small amount of donor hair might want to keep their expectations low, in order to avoid disappointment. However, an ethical hair transplant doctor will always do his best to create the most natural and aesthetically pleasing look possible. In addition to the artistic abilities of the doctor, technical consideration is also important. Some doctors believe that using a certain slit technique, such as the lateral slit, is superior to other methods when it comes to density and packing as many hairs as possible closely together. The lateral slit mimics the way hairs naturally occur, and allows for the most coverage.
Though it is impossible to give exact numbers without a consultation at a hair transplant clinic, about 50 follicular units per square centimeter should be enough to give a satisfactory amount of density. However, it is important to remember that some people might need fewer hairs per square centimeter to achieve the density that they desire, and some others might need more. Also, the fact that hair transplantation is a slow process must be kept in mind, because it is not unusual to undergo several sessions, as many as three, to achieve the density that is desired.
While high density is usually a positive thing, super high densities are not always necessary, because sometimes satisfaction can be met with less, and it is always good to save donor hair for future hair loss and subsequent surgeries. If all donor hair is used in one procedure, there will be little left to use later. Most importantly, regardless of exact density desired, finding a first rate hair transplant doctor to perform the procedure is the key to success.
