Hair transplant density | What is the highest amount of implanted grafts?
One of the most commonly asked questions by applicants who are using hair transplant as a hair loss treatment is “What is the highest hair transplant density?” The answer to this question depends on many cases; but in general, the maximum number of grafts that a surgeon can implant for you is 4,500, which is possible with combined hair transplant methods. Grafts are hair follicle units that usually contain 2 to 3 and sometimes 4 to 5 hairs. That is, the highest density of hair transplants is a maximum of 10 to 14 thousand hairs.
Why are we sharing an article about this topic?
One of the unrealistic promises we see in hair transplant clinic advertisements is the promise of high densities. What is scientifically and practically feasible is a maximum of 4,500 grafts; and any promise more than that can’t be true. Of course, implanting 4,500 grafts is also difficult and depends on two very important factors:
- Characteristics of the patient’s hair and baldness: such as bald pattern, hair quality, strength of follicles, hair bank density, etc.
- Skills, techniques and experience of the surgeon
Both factors are necessary to achieve the highest hair transplant density. Achieving greater densities is possible, but not with a single hair transplant. Non-surgical methods to create high density require re-hair transplantation; which if you prefer you can have them performed about a year after the operation.
Can you reach to normal density with hair transplant?
The answer is NO! Usually you can perform hair transplants when 50% of the hair in the bald area reduces. Baldness is not visually recognizable until more than 50% of the hair has fallen out. For this reason, implanting 35 to 55 follicles per square centimeter is enough to beautify the head. This means that the highest density of hair transplants is relatively far from the normal density; but it is enough to cover baldness. Achieving normal hair density is almost never done, because:
- It’s not necessary to reach normal density to fill the empty areas of the head; and implanting this number of grafts wastes follicles. However, hair loss may continue; so if the surgeon removes many follicles in the initial implant, there are no more follicles left to fill the new baldness.
- Over-implantation of grafts can interfere with blood flow to other follicles. If this happens, your natural hair, which is around the implanted areas, will be shocked and fall out.
- Excessive grafting can cause severe damage or deviation in the blood supply to the scalp. This also leads to scarring and necrosis (cell death) of the scalp.
For these reasons, the highest hair transplant density is usually lower than the normal density. Of course, your condition may be such that you can achieve a close to normal density. This can only be done if your surgeon is sure that the blood supply to the other follicles is not disturbed; and that you will not experience hair loss due to shock.
