Cotsarelis has been highly erroneous, whether you like it or not. False promises and nonsense coming out of his mouth.
Tsuji hasn't till now. Fact. Capiche?
Yes I would destroy him any day about the PGD2 stuff. L'oreal scientists actually already hinted at prostaglandins having some implications in Androgenetic Alopecia back in the 2000 (Bernard et al.). L'oreal later co-funded Cotsarelis his research. We know that prostaglandins have a role in the hair follicle cycle from the 90's too..
PGD2 having a primary role in Androgenetic Alopecia? We'll see how setipiprant will do! Allergan will fail hard both with seti and bima. They don't care though. Kythera brought them Kybella. Ka-CHING $$$! Besides they have enough money.
Prostaglandins having (big) implications in hair follicle cycle function itself, yeah sure. We know that since a long time..But that's not the same as Androgenetic Alopecia.
You say that PGD2 isn't exciting from a treatment POV. Well since it isn't exciting, it likely means it doesn't play a major role in Androgenetic Alopecia? If it did play a major role in Androgenetic Alopecia, the angle would probably be exciting from a treatment POV, and that's what we need. Yet it has been touted by Garza/Cotsarelis like almost some holy grail cure. Not only by forum members.
Cotsarelis his words when Desmond interviewed him in 2014:
I brought up the crowdfunding idea particularly with regards to Follica and he said the amount necessary is quite large. So I insisted on an actual amount and here's what he said:
"US $2 million would bring out a product that would be more effective than Minoxidil and Propecia but would not give a bald person a full head of hair. US $20 million will provide the kind of funding necessary to give someone who is already bald a full head of hair but it will take more years to accomplish".
LOL. I can not even... I still laugh so hard at that statement. A clown statement it is indeed.
I rest my case.
Two teams really matter currently the most:
1. Tsuji & co.
2. Lauster & co. (these guys actually deserve funding too).
