What does evidence show?
Evidence is still limited, but a small RCT of 34 FUE hair transplant patients found 7 days of HBOT at 2.0 ATA reduced itching, folliculitis, and early shedding (27.6% vs. 69.1% in controls), with higher patient satisfaction. At 9 months, graft survival was slightly higher with HBOT (96.9% vs. 93.8%), though not statistically significant. HBOT may support early postoperative recovery, but clear evidence of long-term graft survival benefit is still lacking.
