I figured I would swing back again. I'm pretty convinced of this ****. Everytime I get lazy for more than a few months I start really noticing some thinning. After some period of getting back on the stuff, it goes back to being a little thicker. If anyone reading this doesn't believe it, I don't blame you. I have been convinced more than a couple times that I was fooling myself, stopped using Revivogen, and then quickly went back to it when I started noticing more thinning. But let me add, I was never badly balding. My hairline always stayed nearly the same, but I experienced a lot of thinning throughout the top of my head. I've said this before, but if you're fully bald, I think you would have to use another product, or Revivogen in combo with another product to actually regrow hair.
I'll add this as an update. Over the last year or so I've grown my hair out to nearly shoulder length. I have really curly hair and a lot of the time I pull it back into a "man bun". Now that my hair is longer, the stink of the product is MUCH more noticeable. It must get trapped in the hair in such a way that washing it out is more difficult with long hair. Also, since it is longer (curly haired people will understand) I don't wash it nearly as much as I used to. This has made my window of opportunity to use the product smaller because I don't want to go to work reaking of the stuff.
I wish I had pictures of before and after. It would have been smart and I likely would have stuck with the product more closely. Alas, I don't. But the good news is that this thread is going on quite a few years now, so I feel more confident in recommending the product. I'm on what I would consider a "maintenance schedule" with the stuff, so one order seems to last me forever. I hope the company is thriving because I'm not sure if there is a comparable product out there. Best of luck guys. I'll come back occasionally. If you have a question ask it today because I rarely pop in.
