TLDR Storing hair follicles in a special buffer with certain inhibitors can increase hair growth and improve transplant results.
In a 2004 study, researchers found that hair follicle micrografts stored in HEPES-buffered Dulbecco's modified Eagle's medium (DMEM) with apoptotic cell death (ACD) inhibitors like aminoguanidine (AMG) and 14,15-epoxy-eicosatrienoic acid (14,15-EET) showed significantly increased in vitro hair shaft elongation (HSE) compared to those stored in phosphate-buffered salt solution (PBS). The study indicated that DMEM storage with ACD inhibitors could prevent serum-induced ACD after transplantation, potentially improving the viability and clinical outcomes of hair micrografts. The findings suggest that maintaining physiological metabolic pathways during storage can enhance cell viability, and that pH changes and free radical generation are primary causes of ACD in stored micrografts. The study's in vitro results imply that these storage buffers could be beneficial in hair restoration surgery, although the number of people involved in the study was not mentioned as it was an in vitro experiment.
