hair transplant is less invasive than this, depending though on what you mean by invasive.
What do you mean exactly?
Can anyone please describe the Kerastem procedure? How long does it take, how painful is it, how many doctors/nurses are involved and what do they do exactly and, most importantly, when can you expect to see some results? I thought this consisted of removing fat from the belly and injecting it into the scalp. Surely it is much less painful and less complicated than a hair transplant...
