TLDR High-density hair transplants can have high survival rates with improved techniques, but lower densities might also give good results.
The document presents a study by Nakatsui, Wong, and Groot that investigated the survival rate of densely packed follicular unit grafts using the lateral slit technique in hair transplantation. The study was observational and involved a single patient, with graft densities ranging from 23 to 72 grafts/cm². The study concluded that high-density follicular unit transplantation (>70 grafts/cm²) can result in high hair survival rates due to recent improvements in the transplantation process. However, the commentary suggests caution in using higher densities than necessary, as satisfactory results may be achievable with lower densities (30 to 35 FU/cm²) due to advancements in techniques.

July 2009 in “Current Opinion in Otolaryngology & Head and Neck Surgery” Hair restoration techniques like follicular unit transplant surgery and follicular unit extraction are effective, with ideal graft placement density between 20-30 units per cm². Medications like Minoxidil and Finasteride can help maintain and regrow hair.
