We will be focusing the following quiery “How many number of grafts in hair transplant is required?
Graft calculation in hair transplantation is important for the natural appearance of the transplantation and the optimum use of the donor area.

What is Graft in Hair Transplant?
The graft is the name of the structure with one or more hair follicles and some scalp. Although the concept of graft is often used instead of hair follicles, they are different concepts. While a hair follicle refers to only one follicle, the graft may contain more than one hair follicle. The hair structure of each person is different, so the grafts in each person do not contain the same number of hair follicles. While a normal graft has an average of 2.5 hair follicles, some people may have 3-4 hair follicles in a graft.
How Many Grafts Are Needed in Hair Transplantation?
The number of grafts used in hair transplantation is decided by examining the hairless area, existing hair, the person’s age and the hair in the donor area. Because each individual has its characteristics, the grafts used in hair transplantation differ for each individual. The number of grafts to be taken is directly proportional to the amount of the hairless area in the transplanted area and the hair density in the donor area. The frequency of transplanted hair is important for a natural look. In the most advanced hair loss cases, ten thousand-12 thousand grafts can be found between the nape and the ear. Approximately 6 thousand of these grafts can be used.
If both the front and top areas of the hair have been shed, the minimum number of grafts to be transplanted is 5000, but even this number of grafts may not be enough in some cases. The number of grafts needed to close the small hairless areas solely the temples, sides or forehead is about 1500-2000. Assoc. Prof. Dr. Suleyman TAS recommends transplanting a maximum of 5000 grafts at one session due to these reasons;
1. Local anesthesia over 7-8 hours might be toxic for the body
2. Moving too much hair from the donor area may result in unnatural results. After physical examination, if more than 5000 grafts are needed, another session should be planned to achieve aesthetic goals
