Finasteride
"Started taking finasteride for hair-loss 4 years ago at the age of 22 when the balding became evident. My balding started in the crown area and moved it's way toward the temples, so I am/was a diffuse thinner. I was lucky enough to stop it in time and regrow virtually everything and more with this medication, along with the help of Minoxidil. There are no side effects for me to document. My sex-drive has and is still always in hyper-speed; I have suffered no brain-fog, no ill effects to speak of whatsoever. Besides the price-tag, this medication will save your hair. You have to try it out for yourself. And just to note: there is no possible way for 1 pill to have permanent side effects, do your research."
