I'm planning to look into hair transplant surgery as well.
First thing I would like to point out is the so called "professional" names of the types of hair transplant.
Strip hair transplant - FUE (Follicle Unit Extraction)
Strand hair transplant - FUT (Follicle Unit Transplantation)
FUT is more expensive than FUE because it is more tedious to extract the hairs by strands.
I will most likely be going with FUT because as you said, I don't want scarring. Females would be fine because they can cover it easily with long hair but as a male, that's very difficult. Another pro with FUT is that they can use almost any hair for the implant, meaning if your body hair is thick enough, you can use it instead of using hair on your head! This is important to me as I think removing head hair to add head hair is a bit dumb.
For now, I have 2 clinics in mind, Mega and Maxwell. I heard about from people who have done hair transplant surgery at those clinics respectively. Here are the prices I heard they paid:
Mega - FUT 1000 strands for 2.5mil
Maxwell - FUT 3200 strands for 4.5 mil
As you can see, Maxwell is cheaper and is also one of the more renowned clinics for hair related surgery. They are specialists who only do hair so they would definitely do a good job. The only problem is THEY ONLY DEAL IN KOREAN. If you don't speak/understand Korean, it will be very difficult to go with them. I am desperately learning Korean now so I can try and consult with them when I go to Korea.
