Revivogen worked for me; it decreased my shedding and is slowly starting to thicken my hair overall especially when it was my primary anti-dht for 3 months. I did have a big massive shed about 2-3 weeks after I started, and according to the website, its emulating the same finasteride/dutasteride pattern and means that its working. Although technically it should be stronger than finasteride and dutasteride since it blocks both types of 5AR and the androgen receptor as well,nothing beats finasteride/dutasteride, since they systematicaly work to block 5ar. Although, if you can't use finasteride or dutasteride, revivogen is a very good alternative and if you're using them both like me, revivogen should compliment finasteride's 5ar II blocking in the scalp. In regards to reacting with each other , they shouldn't ; this is from the revivogen website: "Q. I am using Rogaine® and/or Propecia® and don't want to stop using them. Can I use Revivogen at the same time?
Yes. Revivogen is made of all natural ingredients that have no side effects and do not cross react with other medications including Rogaine® or Propecia®. You can safely opt to use Revivogen with other medications." Negatives are that it may be a bit espensive at 30$ a bottle , it has a very bad smell, stains like a b$tch, your hair stays greasy hours later (which is why people tend to apply it at night), bottles may leak ,and the dropper comes apart easy (which is why i use the rogaine dropper).
