Sorry if this is old news, I've never seen it discussed.
Here's the study.
Now, there's a problem with it, which is this:
"The test product, 0.2% caffeine solution, is marketed as Alpecin Liquid by Dr. Kurt Wolff and distributed by the study sponsor Fullife Healthcare Pvt Ltd."
That, of course, doesn't necessarily mean there were any shenanigans and caffeine has been shown to promote hair growth and counteract the effects of DHT in other studies, but it has to make you suspicious.
Now, there's this further issue with it, which is that in this study found the following:
"For caffeine, dose-response experiments showed that a concentration of 0.15% was stimulatory in the MSOCM, but suppressive in the hair follicle model. Also concentrations of 0.05% and 0.01% showed suppression." (Mind you, this study found a hair growth promoting effect at lower concetrations.)
Now they mention the hair follicle MODEL and IDK whether that means that this is a THEORETICAL conclusion, or something that was observed in vitro, I haven't read the whole thing yet.
But anyway, the point is, there are several studies showing that caffeine counteracts the effects of DHT and that it promotes hair growth (even in the absence of DHT) and one suspect study showing it's as effective as 5% Minoxidil.
UPDATE:
The study that tested 0.001% and 0.005% found a greater stimulatory effect with 0.001% than 0.005%, which makes you wonder whether you couldn't get a yet greater effect with a lesser concentration.
UPDATE #2:
I gotta say, guys, this stuff sounds really promising. In this study, they biopsied hair follicles from Androgenetic Alopecia patients and they added testosterone to them and found the expected growth suppression effect and then they took follicles and put testosterone (at levels higher than present in blood) and combined it with caffeine and they found that with a 0.005% concentration of caffeine the follicles exhibited the same kind of growth as controls, in other words, the effect of testosterone was completely negated and with a 0.001% concentration they actually grew more than controls.
UPDATE #3:
I just realized that the study that tested 0.005% and 0.001% concentrations was "kindly supported by Dr Kurt Wolff GmbH, Bielefeld, Germany", the same cat who is selling the product that was used in the study comparing caffeine to Minoxidil.
So, obviously, this throws some suspicion on THAT study as well, but also begs the question, if concentrations higher than 0.005% were found to be inhibitory, why is he selling 0.2%?
