Sure it's the same as in ingredients. But you guys are getting really technical though. I am a long time user of Kirklands and Rogaine[and i'm sure a lot of you are too] and in my honest opinion they are not the same.
Obviously, one is foam, one is liquid[that's since you wanna get technical]. That's already a difference.
One itches way more than the other one, at least for me, Rogaine doesn't itch at all, no matter how much I put at once. Kirkland's itches like hell. One also leaves your scalp flaky[Kirklands]. So yeah, they're the same, sure they are, but you get what you pay for with Kirkland's, which is cheap minoxidil, with the same ingredients as Rogaine. Rogaine dries faster too. Can't really explain it further. You have to buy both yourself and you come back to bump this thread and tell us if they are really "the same". I use both, Rogaine in the day, Kirkland's at night. But honestly i'm about to make a full switch to Rogaine. Kirklands is really nice for my pocket, but not for my head, I can't keep abusing my scalp like that. For years I tried to convince my self that they are the same, being a cheapskate, trying to make myself feel better for buying the cheap stuff. But my scalp has had it, and it has been through enough already. I'm gonna use the remaining 6 bottles of Kirklands I have as much as possible until it ends and i'm not buying it unless I have to.
