This is something most people need to consider in their initial research prior to any transplant procedure.
When we look at all the stunning results posted from any clinic, we think that those results will be achievable for ourselves. When in reality the clinic can only do their part: donor management, graft excision, and hairline/temple/crown design. Rahal and his techs have a good reputation for this from what I've read and seen(10+ years researching). They use magnification and state of the art equipment. Mike- the lead tech has many years with Rahal.
Each persons individual physiology is what dictates how those grafts will take in their new location. Can your body recover fast enough? Can it produce new blood vessels and networks to support new follicles in dormant scalp? How does your skin heal incision wounds? What kind of scar tissue? This is why we see varying degrees of early success and should never judge our own progress with others who may have used the same surgeon/clinic.
Other health factors can contribute also; smoking, alcohol, overall poor health/nutrition.
Bman3082: I think comparing your self to everyone else on this board has caused unnecessary stress.( ive seen all literalno inquiries across many threads) The work looks promising, your own situation may require 12-18 months and I would let it take its course. maybe stay off this forum for a while. Best of luck
