Unfortunately I cannot recommend Dr. Mantse. I had a transplant at his clinic in spring of 2023. He performs his surgeries in a mansion on the outskirts of Budapest and his wife assists him during the procedure.
As you can see from the photos the density is very poor. I had 3000 grafts implanted and I estimate that about 1/4 - 1/3 survived.
One complication I had was that the scabs persisted for up to 5 weeks after surgery. Dr. Mantse explicitly advised against removing the scabs after 14 days instead advising to spray them with salt water daily to remove them, which was a very time consuming process that took 5 weeks in total.
I think this ultimately lead to the poor results. Why? Let's dive into the scientific literature on scabs and graft anchoring
"Bernstein & Rassman (2006): Graft anchoring in hair transplantation" states the following:
"The study showed that for the first two days, pulling on a hair always resulted in a lost graft, but the chance of the graft being removed started to decrease by the third day. By the sixth day pulling on a hair would no longer dislodge the graft. Pulling on an adherent scab always resulted in a lost graft through day five, with the incidence decreasing through day eight. However, by nine days post-op, grafts were no longer at risk of being dislodged."
"Schweiger et al (2015): Highly efficient and compatible shampoo for use after hair transplant" state the following:
"It is crucial to gently remove scabs since avoidance of crusting reduces the occurrence of graft dislodgment during the first 7 days after hair transplant"
"Shichang et al. (2024): Self-management in the post-hair transplantation recovery period among patients with androgenetic alopecia: A qualitative study" state that:
"In the first week post-surgery, gentle fingertip massage should be used to remove scalp scabs."
So contrary to what Dr. Mantse advises scabs can be removed by gentle shampooing and fingertip massages. Prolonging the existence of scabs after 14 days is not beneficial to graft survival and actually detrimental to graft survival, contrary to what Dr. Mantse seems to believe.
Also I  never received the PRP treatment which he gave in his offer.
Given his lack of expertise in the realm of after-treatment I cannot recommend Dr. Mantse
