The document presents the findings of an experimental study on hair restoration surgery, which aimed to evaluate the survival and growth rates of transplanted hair grafts under various conditions. A total of 1020 human anagen hair follicles were obtained from 50 male patients and divided into seven groups, with different preservation methods and types of grafts. The study found that hair follicles preserved in a storage medium (Group B) had a higher survival rate (98%) compared to the control group (Group A) with a survival rate of 87%. Additionally, "plucked" hair follicles (Group E) and follicular units (Group F) showed better growth rates compared to the control group. However, no significant differences were observed between the growth rates of follicles preserved in saline at room temperature (Group C), preserved at 1°C (Group D), or the skeletonized micrografts (Group G) when compared to the control group. The study concludes that the methods tested can be useful for quantitatively evaluating the effects of different procedures in hair transplantation surgery.
