Guys,
I emailed Alpecin about doing a longer (1 year) study at a German University like Jena or Hamburg. They gave me a response that went something "sure, were doing that right now" in so many words. I didnt believe any of it.
Alpecin had one study that took 600 hairs from various balding mens scalps and submitted them to a group with testosterone added, no testosterone added, testosterone and one unit of caffeine, and testosterone and 5 units of caffeine. I believe it took place at the Univ of Jena. The effects were that the caffeine with testosterone group grew about as well as the group with no testosterone. The company said it "protected the hairs" from testosterone's effects. Whether it inhibited DHT from being formed, was a growth stimulant, etc. wasnt even broached.
Whats the problem......STUDY ONLY TOOK PLACE FOR 6-10 DAYS. In vitro too.
Another company study (at Hamburg Univ I think) stated more or less that caffeine helped the skin retain a water layer and combatted ageing in the skin. This is not a suprise. Revlon uses caffeine in its "age-rewind" makeup and I expected that result. Green tea has caffeine, and its finding its way into soaps because of its rejuvanitive effects. This is a long way from growing hair though.
I wanna see a year long in vivo study. See if it regrows a little hair, or at least stops sheddding in men. Ive seen posts on sites saying its helpful, but it has zinc in it, which is a proven DHT inhibitor, and a buch of B vitamins, which are no doubt "good" for your hair. But this is a long way from proving its any more effective than crushing up zinc/b6 and applying it to your scalp (which AINT very effective long term).
The company's vapid little response to me sounded like a lie to my ears. Hey, gourmetstylewellness.com>......if youre listening. Can you email alpecin? Explain who you are, and ask where the studies are takin' place? Tell em' that they will sell units stateside if results are good, and they can explain WHY the product had efficacy? Bet you'll get the two-step from'em though.
