I'm not sure how coffee can affect the use of that drug, but I do know that if you drink coffee, you want to go to the bathroom more often than you normally do . Also caffeine in coffee dilates blood vessels and makes blood circulation faster. I drink only fresh and only ground coffee and use the coffee machine and coffee grinder from this site helixcoffee.com . I am feeling fine and do not have any serious health problem at my 58 .
There are online services that will offer you a prescription and a consult but in the U.S. you do need a prescription.
Don't stress the side effects without even trying the drug. You won't know if you have any issues with it unless you try. If you have side effects, stop taking it. Simple.
You might experience some initial shed as the drug starts to work, but that is typically part of the process. Thinner, fine hairs will shed and be replaced by thicker hair. Don't make the same mistake so many people do where they start on the drug, lose their cool when they start to shed, then freak out and quit before giving it a chance to work. Those people will just continue losing hair in the long run. I have a friend who had a more severely thinned version of your pattern and I told him to start fin and minox about a year ago. He sent me pictures the other day and has had a very nice improvement from drugs alone, but he stuck with it.
There's a lot of debate on name brand over generic. I personally use generic because the difference in cost is insane, but if you can afford the brand name that may be the slightly better option. Generics have the same active ingredient but slightly different formulations for inactive ingredients, so some people won't respond as well to certain formulations as they do to others. I would say this varies by individual.
This is inspiring stuff, thanks for sharing this. One thing that's not totally clear from your regimen...Are you using the minoxidil only after each microneedle session? (So minoxidil approx twice a week?)
