Often it is a false economy. I know of patients having the above graft amounts and it is all over and done in a few hours, multiple technicians punching or drilling away at the same time and then placing the grafts with zero to little actual doctor input.
We would do the same amount over two days and it actually costs less per hour and you have a doctor punching the grafts and cutting recipient sites and not just left to multiple techs to do the A to Z.
Research and meet patients and ask a lot of questions because most of the repair work we do from these clinics, the patient asked zero questions and trusted it all on flashy marketing and celeb endorsements and not on an organic depth of results and online presence, patient history, genuine testimonies etc that established clinics have. Some come and go vey fast and your UK point of contact also can be gone in a flash, I know as this is what I have had reported to me from patients who have been stung and the twitter accounts and all contact gone.
Not having a hair transplant is far better than having a poor one. Take care and all the best in your decision.
