I have learned a lot over the past year and my take on everything here is that:
1). You need to stay committed. If you aren't willing to have a daily regimen, then don't come on here and make us feel sorry for you because you didn't stay committed to fighting hair loss
2). An anti androgen is a must if you have medium to strong hair loss. Without clearing the DHT or reducing the DHT in your body, you'll never be able to grow hair fast enough with a growth stimulant to overcome how badly DHT is breaking down your follicles. Once you have cleared the DHT from your follicles, that is the time you have a limited opportunity during the day to try to strengthen your hair. However, the first battle should always be clear your DHT. If you don't have time to put on a few vehicles throughout the day, then you should focus your time on an Anti Androgen.
3). The growth stimulants, experimental and open market ones are not strong enough for people fighting medium to strong hair loss. I've tried them all and I question if anything is superior over Minoxidil. It's so close that I question if we will ever find a growth stimulant that will be a stand out over the rest. Now there are a few new hopes coming up including NEOSH101 and this newly discovered study that we will have solutions for soon, but things such as Minoxidil, AHK-CU, Bimatoprost, Latanoprost, and a few others are the best we have and they aren't strong enough to regrow hair if you can't clear DHT.
4). Stem cells are the only way to replenish your hair that we know of right now back to true form. In due time, hair cloning will be on the market.
Each person is different but this is my view on things right now. Don't think an expensive regimen will necessarily guarantee you'll keep your hair because it won't. I'm hoping that changes once we do tests on these new products but the odds are that it won't be any different than Minoxidil and the other experimental growth products.
