Effects of Cooling Micrografts in Hair Transplantation Surgery

In the 1999 study involving 240 anagen hair follicles from 10 male patients, researchers found that cooling hair micrografts to 1°C did not significantly affect their survival or growth rates compared to those stored at room temperature (26°C). After a 5-hour storage period and 10 days of culturing, the survival rates were 87% for the control group and 88% for the experimental group, with mean growth rates of 2.68 mm and 2.54 mm, respectively. The study concluded that cooling does not enhance the outcomes of hair micrografts in transplantation surgery.
