Dr. Gho is not being talked about these days very often. You just picked the wrong month to check the boards.
There has been some progress.
In the big picture, I think the biggest difference from 5+ year ago is that we’re now pretty confident that the hairs can be regrown correctly. Whatever we finally get, it will probably have no direction problems, no curl or color problems, etc.
The most serious researchers today seem to have basically licked that issue and now we’re waiting for someone to get it developed & consistent enough to sell commercially. They’re not all pursuing exactly the same methods, but the total range of methods being researched has narrowed down a lot. (In fact one company recently purchased the patents left over from another company’s previous HM attempt.) They’re closer to figuring out what really works and what doesn’t.
Intercytex’s (ICX) well-known program failed in phase#2. By the time the failure was official we had known it was coming for a while.
Aderans (ARI) is nearing the end of FDA phase#2. They’ve got a lot of money behind them and we aren’t seeing any obvious signs of trouble yet.
The Histogen group might be doing even better, but they’re not pursuing clinical trials in the USA. They’re trying to dodge the long & exhaustive process by doing some quick & dirty human trials in southeast asia. It might well very well very soon but that doesn’t give us as much assurance of long term safety (like causing cancer, etc).
