For others out there with this problem, I have been using this minoxidil for about 3 months and it seems to be working. I'm not kidding. I started losing my hair in the crown at about 13 after a bad dietary decision involving sharp weight loss. My patch stayed the same for many years, I did try this previously but I was not very regimented at the time and just assumed it didn't work. Now at 36 I have tried it again and after 3 months I am seeing some fuzz. It's pretty exciting even though it's minimal for the time being. I think my diet still needs tweaking as it definitely seems to have adverse effects when I don't get enough calories. I don't know about the other stuff out there. I have also been brushing it more and using onion in between doses. I actually have video of before but I'm waiting till after it's a bit more full because the original is pretty horrific. I haven't tried laser comb, or prp. I had planed to try prp but I'm holding off to see how the stuff I'm using works. I've been using the WalMart brand so it's only like 15 bucks for 3 month supply.
