He hasn't made an update since July. The last post he made regarding a test subject was this, back in April:
'He is at 5 months post op ( injection of stem cells for hair multiplication ) and so far nothing happened as far as hair growth'
So the test subject is at 11 months now; there should probably be an answer to the question over whether his hair has regenerated with doubling or otherwise. All the test candidates operated on at some point (Boldy, Tom Vercetti etc) all claim their procedures have failed at some time or other.
I want to remain optimistic, as I was a year ago, but all the evidence points to this having failed.
I hope I am wrong. I know Dr Mwamba is trustworthy and I have no intention of disturbing his work, but some kind of update would be nice so we are not in the dark
