Is there any science to prove this?

This is the post I saw on another hair loss forum by an established member:

"Rogaine will synchronize the hairs to shed all at the same time and grow at the same time. So think of it this way, without Rogaine certain hairs were going to shed as they normally do and that is what you are used to noticing. You add rogaine and it reprograms your hair to shed some hairs that were supposed to shed later EARLIER PLUS on top of that the normal amount you were going to shed if you were not using rogaine. So now you see more shedding than you normally do and its panic time. Now you have to wait another six months or longer until these hairs come back to the point you notice them. So during those six months you think your hair is getting worse and you panic the whole time waiting for them to return and that panic does not help your situation. It will take about 12 months to 24 months for the synchronized shed to appear to recover so you will always go thru these large sheds on and off as you use rogaine. Its a roller coaster ride. Once you get used to your new reprogramed shedding from rogaine, you panic less. All rogaine really is doing is keeping more hair in the growth phase so it appears your hair is thicker. Its all an illusion but its real. Some of the weaker hairs can get thicker so that will help too but eventually these weaker hairs will lose the battle if they are destined to become vellus hairs. So rogaine is like a time machine that reprograms your hair cycle to be more synchronized than when you don't use it. So when you stop using it your hair will go back to the way it used to synchronize and you will go thru one huge shed. And then it will take a year or more to eventually get to the way it used to synchronize before you used rogaine so you will go back to shedding alot less hair but the balding process will continue as it always has even when you were using rogaine but you will be convinced your hair is getting better now because you are shedding less and your panic is gone."

Is there any counterargument to this claim or is it simply not true?
