I completely agree with the sentiment and only an idiot would take the media sensationalism headline 'baldness cure' or indeed the promise of 3 years at face value. But it is yet another interesting development in an exciting new field of medical research.
TDS fair point on the last 50 years in terms of hair transplants but that kind of overlooks that the real developments, as in almost every medical field, have happened in the last 15/ 20 years or even more recently. We can clone animals, undertake major organ transplants successfully.... this year we saw the first truly cosmetically acceptable facial reconstruction, a phenomenal surgical first.
Don't get me wrong, none of these are without their side effects or drawbacks and I too am I a realist, but I do think there's a certain truth in there being more promise in modern developments than those we've seen in the past.
